Fixed: Remove o-c-c step from controller/Mgmt

Removing an unnecessary os-collect-config step which may place the
system in a state where it is blocked from initalizing. The step was
originally present as os-collect-config was executed twice by the
playbook as the first run would occassionally fail, but with
os-apply-config step present, the need for the first run is largely
removed, and os-collect-config should now largely succeed on the
remaing execution as the playbook has set the stage for a successful
execution.

The redundant execution was removed as os-collect-config could exit
with a failure that resulted in the playbook halting and marking the
host as failed.  This was due to MySQL being disabled by the
playbook, but numerous steps exeuted by os-refresh-config require
MySQL to be present in a working state of order.
