Make ::tripleo::profile::base classes work with multiple nodes
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
