Code Issues Proposed changes

Make os-instance-action read deleted instances.

Browse Source 
Add a microversion change to the os-instance-actions API so that we
mutate the context to set 'read_deleted="yes"' when looking up the
instance.

This means that
'GET /v2.1/{tenant-id}/servers/{server-id}/os-instance-actions'
and
'GET /v2.1/{tenant-id}/servers/{server-id}/os-instance-actions/{req-id}'
will return instance-action items even if the instance corresponding to
'{server-id}' has been deleted.
