Bug Description

Upstream fixes for https://bugs.launchpad.net/neutron/+bug/1274536 and for https://bugs.launchpad.net/neutron/+bug/1274536 introduced two new configuration parameters:
'metadata_workers' and 'metadata_backlog'.
We need to setup these parameters to production oriented values in MOS.

Per Alex Shaposhnikov comment:
'metadata_workers' - setup it in fuel to some reasonable value, ex. one per 100 planning vm’s
metadata_backlog - set it in fuel to 2048
