ovs-xapi-sync: Retry getting bridge-ids in case xapi is not ready.

When there are multiple xs-network-uuids set for a bridge,
we query xapi to get the record that does not have a VLAN
associated with it. For cases when xapi does not respond,
retry again after a second.

During the times when xapi does not respond, set the value
as external_ids:bridge_id "".

Bug #17877.
