New os-testr uses stestr under the hood, which creates .stestr but not
.testrepository directory in the current dir. Other than that, it
doesn't seem like there is any difference in the format or names of
files generated in the directory.
This patch will fix dsvm failure:
1. The new changes in devstack . Whereby, plugin was not enabled
to use multiple times. Currently, almost functions like fixup_quota,
add_key and add_secgrp enable plugin which runs multiple times.
2. Some functional tests were not working with event/auditing function.
After devstack installation, to run functional test cases, the
nova instance quota, keypair and neutron port quota should be
set to a level which will not block tests. This patch adds a tool
to do this preparation so that developers can easily run
functional tests locally.
Parallel execution of tacker functional test ends up
creating lots of VMs and eventually fails hitting the
default max instance of 10. This fix disables quota for
tacker functional test suite. However gate VMs still has
upper constraint on resources like 8GB max limit. To avoid
tripping the actual gate VM resource limit reduce concurrency
to a lower number (2).
