This object allows to run the "stress" cmdline program in the background
on the specifies run_node, to simulate system load.
To run stress, a test can simply do:
stress = tenv.stress(epc.run_node())
stress.start(cpu_workers=2, mem_workers=1, io_workers=1)
And the test environment will remember to stop it when the test finishes.

this method uses the kpi_analyzer module for analyzing
stdout, CSV metrics and the logfile (if present).
if the module can't be loaded, no KPI will be added.

New patchelf 0.11 release is out and it has fixes hitting us in both 0.9
and 0.10 on different binaries. So let's simply requiring having
patchelf 0.11 in all cases and be done with it (actually, if not running
4G binaries, using 0.9 is enough).

every call to verify_metrics would copy back metrics again. see log here:

this patch only copies back metrics only once. also make sure that, similar
to logs, metrics are always copied back at the end of the run even if they
are not used for metrics checking. this is needed to run the plotting
script.

In order to set up the channel emulator we need to calculate the total
number of RF channels that a eNB has from within a test.

this is helpful to run some action for the exact run time of an iperf3
session. note that if no time spec is given when calling
"prepare_test_proc()", a modifier could set the runtime of an DL experiment
to an arbitrary value so we need to have a mechanism to read
the actual time from within a test

Currently osmo-gsm-tester master jenkins build fails while building
manual due to errors like:
"asciidoc: WARNING: test_api.adoc: line 42: no callouts refer to list
item 1"
According to asciidoc documentation in [1], code examples can be
annotated with callouts, but callouts need to be put inside source code
comments.

tests can now use 'tenv.test().set_kpis(some_dict)' to set any kind of
data as KPIs, which will be presented in the junit report.
The representation of KPIs in the xml file doesn't follow the junit
format, mainly because it has no support for per-test properties.

10s was too short and has still caused tests to fail because they were
stopped just before the iperf finished.
30s seems to be enought and has passed multiple times so far

this refactor no longer enforces blocking operation of the process.
Instead it returns the process object to the caller who
can now run either proc.launch() for non-blocking operation
or proc.launch_sync() for blocking mode.
The non-block mode allos doing other stuff in the background,
for example controlling the rfemu while running a ping.

Timeout value can be specified by test in suite.conf:
config:
suite:

timeout: 2 # 2 seconds timeout

This feature is not really implemented and maybe never was. In any case,
it makes sense to have that working per-test so we can specify different
values per test in case it's needed.

process object always used timeout=300 while runnig wth launch_sync().
Let's allow replacing that value beforehand so that iperf3 can
pre-configure the process object and caller doesn't need to care about
calculating expected time.

Otherwise processes using the link like "ping" or "iperf3" may fail
because there's still no IP address assigned.

Setting the log.ctx manually is not needed anymore and it's actually
harmful since all palces where it was used, a log.Origin already in path
was being passed, causing a origin loop.

Use tailored sample rate only use for 6, 50 and 75 PRB. For all other bandwidths,
we use the full LTE rate and downsample.
With 5.76e6 as base sample rate, for example, we had some issue during the tests like:
[zmq] Error: tx time is 0.178 ms in the past (7833600 < 7835648)
[zmq] Error: tx time is 0.011 ms in the past (7835520 < 7835648)
Using a higher sample rate seems to work better.

the overhead with 6 PRB and MIMO is a bit higher when compared
to other PRBs resulting in lower achievable throughput
