Add profiler support into Tempest

The primary goal is to be able to run all Tempest tests
and verify OpenStack when profiling is enabled. Also this patch
allows to:
 * manually verify that certain services are properly instrumented
   and produce trace events when a scenario is executed;
 * write automatic tests for trace coverage;
 * profile certain tests from performance perspective.

A new parameter is introduced into tempest.conf:
 * profiler.key - the key used to enable OSProfiler (should
     match the one configured in OpenStack services)

To test the patch on DevStack:
 1. Enable osprofiler with Redis collector in local.conf:

   enable_plugin osprofiler https://git.openstack.org/openstack/osprofiler master
   OSPROFILER_COLLECTOR=redis

 2. Run all Tempest tests or select some, e.g.:

   tempest run --regex tempest.api.network.test_networks.NetworksTest.test_list_networks*
