upgrade:
- |
Switched the default value of the ``metadata_workers`` configuration
option for the OVN metadata agents to 2 (from $::os_workers). While
the OVS metadata agents runs on the controllers/gateway nodes (and
defaults to $::os_workers) the OVN metadata agents are distributed
and runs on the compute nodes instead so, there's no point in running
dozen of them on each compute. Also, by reducing the number of workers
we also reduce the burden on the OVSDB that the OVN metadata agent
connects to making OVN more scalable.
