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

rename UE helper functions to query RRC connected/idle state
and adapt tests accordingly
also add helper to retrieve assinged IP address

the default value of 60s is too long to trigger errors in the handling
of this timer. So a 5s timer is more likely to reveal potential issues
during the test execution

It turned out that the Amarisoft and SRS eNB scheduler produces
slightly different maximum data rates for both UL and DL.

This way tests which require a very specific config file can override
specific template files used by object classes.

After this commit, in some situations ssh related errors are printed
directly in the exception to quickly find cause of the issue.
Example:

That's not needed and will produce some parent loop detection in
log.find_on_stack() if logging is called under that stack frame.

when calculating the dl and ul bitrate, it is required to take the
sum of all active component carriers since they are reported seperately
inside the CSV file

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.

tgz files in trials can be categorized in subdirectories, allowing to
select different bianry files at runtime based on the target run node
which is going to run them. This way for instance one can have a binary
linked against libs for eg. CentOS under run_label "centos/" or an ARM
target under "arm", and then use "run_label: arm" on the resource using
it.

Since the process is run in the background through the wrapper bash
script, stdin was disabled there. By explicitly redirecting the bash
process stdin we make sure it is always able to read from it.

we've only waited when running with ZMQ but in fact we need
to always wait because the UE may need some time to
gracefully exit, i.e. send the detach request and shut down correctly.
this is checked in cleanup() and verity_metrics(), so also before copying back
the CSV metrics. But we only wait once.

this allows to sum dl_brate and ul_brate and perform
the known operations, like max, average, etc. on both
UL and DL bitrate combined
For examples, with this CSV ..

.. one could calculate the average of DL and UL bit rate with:
ue.verify_metric(1e6, operation='avg', metric='dl_brate+ul_brate', criterion='gt', window=test_duration)
and veriy that it's average is greater than 1 Mbit/s
Change-Id: I5c7c80bb107fa6b93b215176e6ebbb5dc8594860
this allows to calculate the rolling average over a specific
window in time and take the maximum of that
this is useful to get average value for 30s UDP traffic for
example from the UE metrics
