This adds a functional test which recreates bug 1839560
where the driver reports a node, then no longer reports
it so the compute manager deletes it, and then the driver
reports it again later (this can be common with ironic
nodes as they undergo maintenance). The issue is that since
Ia69fabce8e7fd7de101e291fe133c6f5f5f7056a in Rocky, the
ironic node uuid is re-used for the compute node uuid but
there is a unique constraint on the compute node uuid so
when trying to create the compute node once the ironic node
is available again, the compute node create fails with a
duplicate entry error due to the duplicate uuid. To recreate
this in the functional test, a new fake virt driver is added
which provides a predictable uuid per node like the ironic
driver. The test also shows that archiving the database is
a way to workaround the bug until it's properly fixed.
NOTE(mriedem): Since change I2cf2fcbaebc706f897ce5dfbff47d32117064f9c
is not in Stein this backport needs to modify the test to use
the global set_nodes/restore_nodes which means we can remove some
of the startup hackery at the beginning of the test. Also, since
FakeDriver.set_nodes does not exist in Stein we have to modify the
FakeDriver._nodes variable directly (the global doesn't affect that
after startup).
