This patch adds support to start_ovsdb() function in ovn-ctl to
start the
ovn db servers in standby mode. This can be done in the following ways
1. Use parameters --ovn-nb-sync-from-addr and
--ovn-sb-sync-from-addr to
set the addresses of the master server.
2. Create files $etcdir/ovnnb-master.conf and
$etcdir/ovnsb-master.conf
with the tcp url of the master servers.
If --ovn-nb-sync-from-addr and --ovn-sb-sync-from-addr is used, it
will
overwrite the contents in the $etcdir/*.conf and use that server
as the
master.
Additional functions to promote a standby server to master and demote
master server to standby mode are also added in this patch

In the context of OVSDB HA, we have been calling the ovsdb-server pair
as active/backup.
It would be nice if we can avoid using another term "master". I have
no strong preference
for "active", just want to avoid using another term.
I will change it in the next revision.
It seems that if demote_ovssb() is followed by restart_ovsdb(), the
role switching
won't be respected. true?
You are right Andy. I will fix this too.
Thank you
Thanks.
