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

bootstrap_nodeid is a parameter looked-up with Hiera but only set on
controllers. With the transition to composable roles, we don't need to
set this parameter on compute nodes, so let's just default this value by
undef so we can deploy Neutron classes on compute nodes.
