- Provide API URL when returning status to inform plugin or mobile app

# What this PR does
It introduces soft-delete of organization, since grafana stacks are
soft-deleted too. Also, we had a problem with deleting orgs with large
amounts of alerts, so soft-deletion will fix this problem. I think, that
problem of cleaning alerts of deleted orgs should be solved as a part of
alert retention
