Mathieu Bultel a59a188a6b Force ansible serial to 1 for the Controller
By introducing update_serial variable we parallelize update
execution on non-pacemaker enabled nodes. Custom role data users
need to update their role files. By default we do serial 1 making
sure nothing changes for users who didn't update their role data.

The new role variable update_serial is introduced
allowing parallel update execution. On Controller
role this variable defaults to 1 as pacemaker
has to be taken down and up in rolling fashion.
The default value is 25 as that is default value
for parallel ansible execution used by tripleo.
