Changes

osmo-msc: Use osmo-mgw instead of osmo-bsc_mgcp
osmo-msc now requires osmo-mgw and it's not expected to work properly 
anymore with old mgcp code.

osmo-trx: Add cfg template
Since commit 3da1f8352e337fb032bf7a58c2909d3ba918e237, osmo-trx requires 
a cfg file to start successfully.

the defaults.

modem: get IMSI from ofono
There's no need to specify the IMSI manually in resource config and it's
also prone to errors. Let's take it from ofono. Add a 'sim' feature to
allow modem to auto-discover it, otherwise if not supported leave that
feature out of the config for that modem and an imsi can still be
manually providen.
Change-Id: I20f9e8d97775293925205e4ea576d814214bf1a8

example: Maintain different resources.conf for RnD and prod
We still want to maintain this file in the same osmo-gsm-tester repo 
because we frequently neef to update the config when adding new 
features.
Until now only 1 file was maintained (which was used for RnD setup), and 
then when runnin in prod the jenkins script used sed to change the file 
to accomodate slightly changes. This way is too hacky, so let's just 
maintain too separate files, keeping the original resources.conf key 
name used by osmo-gsm-tester free, so that jenkins job can symlink one 
of the 2 files to it.
Take the chance to remove OctoBTS and Sysmocell5k from the RnD resources 
file, as we don't have those them.

modem: workaround ofono crash
Since commit bfd0b2310cf09e32cb7d5dbe74ec57606a7d2aab, the IMSI is 
retreived from ofono. To get the IMSI, the modme must be powered ON 
previously. The imsi() method is called before calling connect() in 
order to set up the IMSI in the HLR. As a result, the following 
behaviour occurs:
- Powered=true (in imsi())
- SimManager.GetProperties() (several of them)
- Powered=false (power_cycle() in connect()
It seems powering off the modem immediately after using the SIM service 
makes ofono crash. Proof of it is that crashes were seen mainly on tests 
using only 1 MS, in which we don't spend that much time between 
SimManager.GetProperties() and Powered=false for the same modem.
Let's workaround the crash for now increasing the time between using the 
SIM services and powering the modem off.

Create Pcu abstract class and make OsmoPcu inherit from it

Introduce PowerSupply interface and PowerSupplySispm
File powersupply.py defines the interface to be used by child classes 
implementing it. It also provides helpers to allocate a child class 
based on configuration provided ('type' field).
File powersupply_sispm.py is an implementation using pysispm [1], as
it's the one used to control the programmable power socket we have right
now.
This kind of class will be used in later commits by Nanobts class, as we 
want to poweroff the Nanobts completelly when not in use.
Using it requires the following extra dependencies:
$ apt-get install python3-usb
$ pip3 install pysispm

event_loop: Use glib as mainloop impl and move modem to use event_loop
Several benefits:
- We can add APIs to poll on fds in the future (for smpp socket for
 instance) instead of using busy polling.
- During wait(), we now block in the glib mainloop instead of sleeping
 0.1 secs and not handling events during that time.
- We remove glib mainloop specific bits from modem.py

nanobts: Attempt at fixing race condition using ipaccess-config after
power up
It seems there's a period of time in between the nanoBTS starts 
announcing itself and it can actually be managed by the BSC
(ipaccess-config in this case). If ipaccess-config is called quickly 
after nanoBTS it first announced, its TCP conn will be rejected with a 
TCO RST, and ipaccess-config will fail. Let's see if waiting a few 
seconds is enough to have this working more reliably.

ms: Create a cumulative distribution function class
We are using the CDF to decide which percentage of the jobs should be
running at a given point. The x-axis is time and the y-axis the 
percentage of how many jobs should be running.
There are three functions to do this. The first one is a constant which
would result in everything being started right now, one to start them
linearly and the last (formula from Qt/3rdparty) to first accelerate and
decelerate slowly.

ms: Create a simple epoll (or kqueue) based event loop

select/epoll or kqueue. It should scale to many open fds but we will not
have that many.

ms: Create an event server to handle Unix datagram messages

incoming datagram messages. The lua remotes are not passing credentials

ms: Add a first test to use all parts of the system
This is an interim solution but is bringing all parts together. We will
need to:
 * Abstract this into a base class
* Be able to mix different tests without interfering with each
  other (e.g. 10k LU tests, 2k SMS sending)
* The event loop will need to handle multiple timers/timeouts
* Stats printing should print more information and test pass/fail
* The test should quit early if everything has already passed

ms: Add a main function to start all of it
Add a main file to start everything. All parameters need to be made
configurable. Composition of testcase and IMSI ranges need to be

event_loop: Avoid leaking active timeouts on poll exception
It was spotted that when an error ocurred during poll generating an 
exception to finish the test (osmo-msc ended prematurely), then the 
active wait() condition was kept being checked for later tests, making 
all followup tests fail.
That's because in case of exception we were not making sure the timeout 
is removed and it kept firing forever.

modem: Catch exception: call removed while waiting to become active
This can happen while in a test we use: wait(ms_mo.call_is_active,
mo_cid)
And then answer fails for whatever reason, after a timeout ofono will 
remove the call object:
/sierra_2: DBG: 'org.ofono.VoiceCallManager'.CallRemoved() ->
/sierra_2/voicecall01
As a result, during next call o call_is_active() will try to get the 
call object, but it doesn't exist anymore and an exception will be 
created in method call_state during call to systembus_get().

bts: Allow setting amount of TRX and timeslot in cfg and from test at
runtime
The num_trx attribute for a given BTS states the number of TRX to be 
used by that BTS. If more than num_trx are configured in trx_list in the 
cfg file, then only up to num_trx are taken into account. If a num_trx 
value higher than max_trx is specified throuygh config file or at 
runtime by the test, an exception is raised explaining the issue.
The num/max_trx attributes are overlayed along the config levels
(generic -> bsc_bts -> specific bts-type -> specific resource object). 
This way we can specify a long list of trx+timeslot config in the 
generic config (bsc_bts), and tune for each model and specific BTS which 
is the desired default number of TRX, as well as the maximum supported 
per type.

Unload suite local modules after suite exit to avoid collisions
Since sys.path is modified idynamically to load modules from "lib"
subdir of each suite, from python env point of view all those modules
share a namespace. As a result, there can be name collisions.
If a name collision appears (eg test1 loads "testlib.py" and test2 
afterwards also loads its own "testlib.py"), then python interpreter 
thinks the testlib.py module is already loaded, so test2 ends up using
"testlib.py" from test1.
The way to solve this is to make suite local modules to live only
through the scope of the suite, and unload the modules once the suite is
finished.
