Currently, sahara's db-sync is run on every node. We should instead
run it if we're on the bootstrap node as race conditions may occur
and these will cause issues.

As we are staring to manually check overcloud services
the first step is to check that the puppet profiles
are all aligned.
Changes applied:
No logic added or removed in this submission.
Removed unused parameters.
Align header comments structure.
All profiles parameters sorted following:
"Mandatory params first sorted alphabetically
then optional params sorted alphabetically."
Note: Following submissions will check pacemaker,
cinder, mistral and redis services in the base profiles
as some of them has the $pacemaker_master parameter
defaulted to true.

In the Next Generation HA architecture a number of active/active services
will be run via systemd. In order for this to work we need to make sure that
the sync_db operation only takes place on the bootstrap node, just like it is
done today for the pacemaker profiles.
We do this by removing sync_db as a parameter and instead set it to true
or false depending if the hostname matches the bootstrap_node as it is done
today in the pacemaker role.
Note that we call hiera('bootstrap_nodeid', undef) because if a profile
is included on a non controller node that variable will be undefined.
The following testing was done:
- HA puppet-pacemaker.yaml scenario with three computes
- NonHA with one controller
- NonHA with three controllers

In order for each service to operate independently when used with Pacemaker,
the roles needed to be separated.
This also drops all pacemaker constraints, as they do not make much sense
in the composable realm.
