Do not filter image list from glance api

Horizon filter glance image list because 'aki', 'ari' type of images
can not be launchable.

However, it is better to provide full capacity with glance in
Horizon.

Reasons:
1. Horizon allow upload those images. It brings confusion if not
show them
2. The filtering strange behavior when pagination is enabled

Changed to show all images in Horizon, but 'aki', 'ari' type of
images are not allowed to launch or create volume.

Remove Create Backup Action For Non-Active

the "create backup" action is incorrectly shown for a non-active
database instance in the database instances table. now, only if the
instance is active, will the action/button appear.

in addition, non-active instances are now excluded from the dropdown
in the create-backup workflow.
