testenv: fix 'container crashed' detection

* When the testsuite stopped and using podman, check if it stopped
  because the container crashed and raise an exception.

* Even after 9eb5e696 ("testenv: make podman stop more robust") it
  happens sometimes in jenkins that the container gets stopped on
  purpose because the testsuite is done, but then the watchdog process
  prints an error saying it crashed (without actually stopping testenv
  at this point). Change the message to a debug message that just says
  it stopped, this should not be an error.

testenv: podman-main: set watchdog timer to 60s

Increase the timer from 10s to 60s, as with 10s I see jobs failing with:

  ERROR: /tmp/watchdog was not created, exiting

In theory 10s should already be enough, my guess is that if a jenkins
node is currently under a lot of load then the feed command may take
several seconds and so we hit the previous timer. Even if this is not
the cause, I think it is good to rule it out.

Exiting after 60s if the jenkins job was (manually / with connection
loss) aborted is still relatively quick.

statsd: Support f_statsd_snapshot() API when using VTY-triggered stats report

Until now that API was only used in testsuites which relied on
time-trigerred reports. This commit also supports getting a given
snapshots if the IUT is configured to only trigger a report based on VTY
request.

hnbgw: Introduce module parameter mp_pfcp_upf_node_id

This will allow using it later in HNBGW_Tests.ttcn file when waiting for
PFCP Assoc Req.
