we've added the modifier to configure Amarisoft eNB channel
model. This patch enables it for srsENB.

this avoids a false negative detection when the UE attach takes a bit
longer and the first seconds all zeros are reported in the CSV
the HO test, for example, would fail in such a case as it expects
no zero TP over the course of the experiment.

the WS is closed if the eNB process dies. this patch will log an
event but not stop the experiment.

we've noticed that the Iperf client times out too soon in
some experiment. It seems that this happens with ZMQ if
the RAT is too slow (slower than realtime) and the eNB buffers
too much data. This causes iperf to still receive DL data
for example long after the configured runtime.

Since a while ago, we avoid by default using the --logfile param to log
the json output to a different file, in order to stay compatible with
older versions of iperf3.
However, the local logfile was still being created, and was not
overwritten with the remote file with content because there's none
created remotely (due to reasons explained above).

when phy.signal=1 is set in the log_options, the eNB will dump
a binary file that needs to be copied back as well

this avoids issues when the channel emulation stops in the middle
of a high attenuation values and the device is left in this state.

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
Change-Id: I484a0add322ffd269a1e9df72a00cf348950b268
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.

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.

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

specifiying the rx/tx_freq for the eNB is optional. But when
it's done it needs to be correct. There seems to be an issue
when mapping the freq[0-3] between srsENB and Amarisoft eNB.
So it's safe to just drop the config here altogether.
