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

Simplify the base neutron profile so that we always include
the neutron and neutron::config classes at step 3. In doing so
we can now simplify the pacemaker version to use a simple include
which will avoid duplicate class errors.

neutron::server requires the neutron's init.pp to be ran beforehand
because init.pp installs the 'neutron' package. Else the relationship
with neutron::policy will fail [1].So to address this, we move
neutron's init.pp to be ran on step 3 if db_sync is enabled.

Implements: blueprint refactor-puppet-manifests
Add neutron profiles for both pacemaker and non-ha.
HA profiles are designed such that they include the base
profiles, disabling features as needed, while the base
profile can be used independently.
