smdpp_Tests: rename smdp_server_url to smdp_server_fqdn

The member name "smdp_server_url" is technically not correct as the
content is an FQDN. Let's rename it to "smdp_server_fqdn".

Let's also put a comment in which we explain why FQDN is hardcoded
and not available as configurable module parameter.

smdpp_Tests: simplify generation of smdpp_ConnHdlrPars (NIST vs. BRP)

When we call f_init_pars() it will return a record with default parameters.
However, those parameters are only a suitable default when the NIST curve
is used. For the brainpool curve we will have to modify returned result.

Let's simlify this by adding a parameter to f_init_pars() that allows us to
switch between the defaults for NIST and BRP as needed.

hlr: pyhss: create/delete subscribers

Run the PyHSS API service, and fill it with a default APN on startup.
Having one APN entry in the database is required for creating
subscribers.

Talk to the API service for creating and deleting subscribers. Do this
with a new script pyhss_api_helper.py. Deleting subscribers requires
reading JSON returned from the server (to get the AUC and subscriber ID
from the IMSI). I have first attempted to do this via HTTP_Adapter
instead of using a helper script, but this was a lot more complex and
would have required to have the JSON structure in the TTCN3 files. The
eim testsuite also runs an external script for REST requests.

With this change and additional fixes in PyHSS, more tests pass:
* HLR_Tests.TC_gsup_sai
* HLR_Tests.TC_gsup_sai_num_auth_vectors
* HLR_Tests.TC_gsup_ul
* HLR_Tests.TC_gsup_purge_cs
* HLR_Tests.TC_gsup_purge_ps
