Add needed swift storage dirs for packaged install

These directories are needed by both the packaged and source installs,
so do their creation into a common install.d script instead.

Ability to add *-create-dir service separately

For systemd services, we create 2 services: one for the daemon and one
that creates the run directory under /var/run for the daemon.

For the packaged installs, the daemon service is already provided by the
package, so we need the ability to add just the *-create-dir service.

Some might say that the package should create it's run directory...and
it in fact does. However, we are reconfiguring the services to use
/var/run and the package uses /var/lib. Since /var/run is tmpfs mounted,
we need the *-create-dir services for the packages as well.

Add create-dir service for neutron

The service will ensure /var/run/neutron is created and neutron owned,
which is required by the neutron daemon.

Add create-dir service for nova

The service will ensure /var/run/nova is created and nova owned,
which is required by the nova-compute daemon.

Fix neutron package install

Previously the neutron element was installing neutron-server. This
should actually be happening in the neutron-server element itself.
Likewise, the neutron-dhcp-agent should also install the package it
needs. In both cases, the package is just openstack-neutron, but only
the intended services will be enabled and started due to the
os-refresh-config scripts. E.g., if you only include neutron-dhcp-agent,
and not neuton-server, only the neutron-dhcp-agent will be enabled.
