While the patch where this was first introduced and set to 120 [1] is
sensible for the vast majority of jobs, it's conceivable that some
jobs might want a different value.
Specifically, the whitebox-tempest-plugin changes configurations and
restarts Nova services, and to do so it waits for the service status
to update in the API before continuing with the tests. With the report
interval set to 120 and the down time threshold set to 720, the
service would continue showing 'up' in the API long after it was
actually down, causing the wait to time out.
Whitebox is a low-traffic project with only a couple of devstack jobs
that run tempest tests sequentially (concurrency=1). Its CI is also
pretty stable. It seems legitimate for it to keep the old default
values of report_interval and service_down_time.
This patch keeps the 120 default for NOVA_SERVICE_REPORT_INTERVAL, but
makes it configurable by individual jobs. Since the original patch
also introduced CINDER_SERVICE_REPORT_INTERVAL as a constant, make
that configurable as well.
