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.
