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

These can be controlled via the specific Pacemaker role template.

Before the roles we could make the create db operation depend on a
'galera-ready' resource [1]. We can't do it anymore from the role so
we need to do create in step 3, when we do sync as well.

This change moves the database creation and sync with the role
profile, so that it's only executed when the role is enabled and
by the role itself.
It also calls the non-pacemaker profiles out of the 'step'
conditional because the non-pacemaker profiles know how to deal with
'step' already.
