In a recent patch [1], a bug in the zone migration strategy was fixed,
which prevented audits using this strategy to create action plans
with both instance and volume migrations. We documented this limitation,
but forgot to remove the note when fixing this bug.

Despite having the src_type paremeter for the storage_pool dictionary as
a mandatory parameter, the value is not being used to filter the volumes
to migrate, using only 'src_pool'.
This change makes 'src_type' optional, since it was ignored until this
point, making it optional keeps the same behaviour by default. If
'src_type' is in the audit parameters, the strategy uses both 'src_pool' and
'src_type' to filter the volumes to migrate.

Unlike Nova, Cinder does not support calling the 'os-migrate_volume'[1]
action without a host or a cluster. For volume migrations of type
'migrate' in watcher the dst_pool is required, but for other migrations
that migrate the volumes to different types is not needed. This
change checks if the dst_pool is defined and prevents some migrations
when it's misssing information.
Adds testing for creating audits with the Zone Migration status,
validating the schema changes.
