testenv: support obtaining talloc reports

Allow setting vty_port= and vty_host= (default: 127.0.0.1) for SUT
components in testenv.cfg. Pass the values as OSMO_SUT_PORT and
OSMO_SUT_HOST to the testsuite, so ttcn3-tcpdump-stop.sh generates
talloc reports after running test cases.

The next patch will add vty_port/vty_host to existing testenv.cfg files.

I have considered enabling the talloc report only conditionally (e.g.
with a --talloc-report parameter). But previous behavior in
docker-playground was also that we created them unconditionally where
OSMO_SUT_PORT/HOST was set, and they are generated almost instantly so
it did not seem necessary to make this conditionally.

*/testenv.cfg: add vty_port, vty_host

Add these variables, so a talloc report can be obtained after running
test cases.

HTTP_Adapter: Rename s/g_pars/g_http_pars/

The HTTP_Adapter component is a probable candidate to end up as part of
another component extending it, like the Prometheus_Checker coming up
soon.
Since the fields in HTTP_Adapter are available to subclass components,
that means they cannot use the usual "g_pars".
Rename the self-enclosed "g_pars" in HTTP_Adapter to let subclasses use
it.

Misc_Helpers: Introduce API helper f_str_startswith

Counterpart of f_str_endswith(), this API is usually available in
several programming languages like python, and it's handy to have since
it's usually used and hence dev doesn't need to think on how to
implement it using regexp, etc.

This API will be used in a follow-up patch implementing Prometheus
metrics checker module.

Introduce Prometheus_Checker module

This module serves the same purpose as the existing StatsD_Checker.
It will be used in open5gs, which so far exports its metrics using
Prometheus.

hss: Initial validation of Prometheus metrics

diameter metrics.
