[ovn] Add timeout option to ovsdb-client command
Today, we invoke ovsdb-client to cleanup the MAC_Binding entries without specifying any timeout. This can lead to workers blocking forever if there's an issue with the connection to the server. This patch is adding a timeout parameter to the command line to prevent this condition.
