[PATCH v2 1/4] PerfRepoUtils: add support for RR test in perfrepo templates

[Jiri Prochazka]

This patch adds test_type param to all PerfRepo template functions. When
this param is not specified, it is expected the test to be *_STREAM and
metric labels are throughput, throughput_deviation, etc. When the param
is set to RR, metric labels used are rr_rate, rr_rate_deviation, etc.

This is needed for the new short-lived connections test, where the unit
we measure is not throughput but request/response rate.

[PATCH v2 2/4] test_modules/Netperf: fix regex for parsing RR threshold

[Jiri Prochazka]

There is an extra dot in regex for parsing RR threshold value. This
patch removes it, so the parsing works now correctly.

[PATCH v2 3/4] test_modules/Netperf: make test recognition prettier

[Jiri Prochazka]

In _parse_threshold() the recognition of test type (STREAM and RR) is
done via long if statement, when we only need to check for STREAM or RR
in test type name. This also fixes TCP_CRR test threshold parsing as
that test type was not present in the if condition.

[PATCH v2 4/4] recipes/short-lived_connections: add test

[Jiri Prochazka]

This patch introduces new test for testing short-lived connections. The
topology is the same as in regression-tests/phase1/simple_netperf test.
It's two baremetal hosts, each with one NIC. Measurement tool is
netperf, test types are TCP_RR and TCP_CRR. For both test types, the
test is run with these Request/Response sizes: 1K, 5K, 7K, 10K, 12K.

The test does have working integration with PerfRepo and uses all
aliases used in regression-tests/.

--
Changes in v2:
* Moved the test to regression-tests/phase3/.
* Added README file
* Fixed undefined variables typo
* Prettier module update
* Removed redundant 15s wait

+
+PerfRepo integration:
+    First, preparation in PerfRepo is required - you need to create Test objects
+    through the web interface that properly describe the individual Netperf
+    tests that this recipe runs. Don't forget to also add appropriate metrics.
+    For these Netperf tests it's always:
+    * rr_rate
+    * rr_rate_min
+    * rr_rate_max
+    * rr_rate_deviation
+
+    After that, to enable support for PerfRepo you need to create the file
+    short_lived_connections.mapping and define the following id mappings:
+    tcp_rr_id -> to store TCP_RR Netperf test results, maps to TestUid of a PerfRepo
Test object
+    tcp_crr_id -> to store TCP_CRR Netperf test results, maps to TestUid of a PerfRepo
Test object
+
+    To enable result comparison against baselines you need to create a Report in
+    PerfRepo that will store the baseline. Set up the Report to only contain results
+    with the same hash tag and then add a new mapping to the mapping file, with
+    this format:
+    <some_hash> = <report_id>
+
+    The hash value is automatically generated during test execution and added
+    to each result stored in PerfRepo. To get the Report id you need to open
+    that report in our browser and find it in the URL.
+
+    When running this recipe you should also define the 'product_name' alias
+    (e.g. RHEL7) in order to tag the result object in PerfRepo.
