Matt Riedemann f292a92a89 Add functional regression test for bug 1837955 
This adds a functional regression recreate test for
bug 1837955 which was introduced with change
Iae904afb6cb4fcea8bb27741d774ffbe986a5fb4 in the Queens
release.

In this scenario, the primary (and potentially alternate)
hosts for a server build fail and reschedule to conductor.
Eventually all alternate hosts are exhausted and specifically
trying to claim allocations against the alternates fails,
probably because between the time of initial scheduling and
rescheduling something else took up the spare capacity on the
alternate host.

When this happens, MaxRetriesExceeded is raised but the
instance is stuck in BUILD status rather than set to ERROR
status with a fault message.

NOTE(mriedem): In this backport the test is changed slighty
since change Id8b5c48a6e8cf65dc0a7dc13a80a0a72684f70d9 is
not in Rocky so the ProviderUsageBaseTestCase.neutron
attribute does not exist.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

Developers

For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.

Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests.
