Octavia is struggling with proper handling of DB connectivity issues bringing down all running loadbalancers. Octavia tries to failover amphorae and can fail in one of the following stages: 1. Octavia can't create new amphora because Nova isn't ready yet after DB outage. Nova-API throws 500, Octavia nukes amphora instance and won't try to recreate it again. 2. Octavia tries to recreate amphora instance but it gets stuck in PENDING_CREATE forever. 3. Octavia fails completely reporting DB connection issues, leaving some amphoras in error, some in pending_delete as bellow: It affects also HA deployments. This patch fixes that by wrapping the DB check for health, waiting for the connection to be re-established and sleeping off the full "heartbeat_timeout" interval.
