Searchlight not updating on member change

[Travis Tripp]

If you create an image and later change its members, the members are not updated via notifications. You have to run the index sync again to get the updated member list.

See: https://bugs.launchpad.net/searchlight/+bug/1490697

Membership information is critical for horizon filtering. Typically, a person is allowed to view an image under the following conditions:

 1) The image is owned by the project I am currently logged into.
 2) The image is public
 3) The image is owned by another project which has added me as a member and I have accepted membership to it.

Without current membership information, 3) above is not possible.

CLI command to do image membership on devstack:

 # Pick an admin image ID and a demo project ID
 source ~/opensource/openrc admin admin
 glance image-list
 openstack project list

 # Share the image with the demo project using:
 glance member-create <image-id> <project-id>

 # switch to demo project and accepted the sharing
 source ~/devstack/openrc admin demo
 glance member-update <image-id> <project-id> accepted

 # Verify in listener and in results
 # You can re-trigger by updating status again to pending
 # and then back to accepted. Introspect searchlight
 # between them.
 glance member-update <image-id> <project-id> pending
 glance member-update <image-id> <project-id> accepted

Glance doesn't issue a notification on image member changes. We'll have to see if this is something they'll entertain.

    Add --no-delete to indexing

    To support cases where it's desirable to index without deleting data
    and mapping, add a --no-delete option to 'index sync'.
