More horizon changes

This commit does the following:

- changes /static alias and COMPRESS_ROOT to
  {{ install_lib_dir }}/static/ (since this is where collectstatic
  writes to)
- removes bundled manage.py and copies it out from {{ git_dest }}
- runs horizon-manage.py compress --force as per Issue #108 fixed in
  stable/icehouse
- removes some symlinks we drop in v9.0.0 since having those in place
  cause horizon-manage.py collectstatic to fail
- remove chown of {{ install_lib_dir }}/openstack_dashboard and
  {{ install_lib_dir }}/horizon since Apache should only be writing to
  {{ install_lib_dir }}/static/
- restrict Directory directive to
  {{ install_lib_dir }}/openstack_dashboard/wsgi/ since nothing Apache
  shouldn't need any further access under
  {{ install_lib_dir }}/openstack_dashboard/w
- remove all Options from {{ install_lib_dir }}/static Directory
  directive since those shouldn't be necessary
Include a [clients_glance] section in heat.conf

To ensure that heat uses the internalURL endpoints for glance it is
necessary to explicitly include the [clients_glance] section in the
configuration.

Revert 17c5ee87

This change effectively reverts 17c5ee87, but leaves in some additional
comments added by that commit.  We also update the cloudserver-aio.sh
script to reflect this reverted change.

As to why this change is no longer needed, the assumption that needing
a separate cloud files tenant ID to form your glance swift user name
was incorrect.  Using the format of <cloud_tenant_id:cloud_username>
works fine.

Closes issue #281
Default to creating agent token for each entity

Currently, we require the operator to specify an existing agent token
to use for all entities.  This means the operator needs to make a call
to MaaS to determine the agent token ID before being able to deploy the
environment.  This change creates a new agent token w/ label matching
the entity in question and configures the agent to use that token.  If
the user variable maas_agent_token is defined, then we skip creating an
agent token and use the token specified.

Fix incorrect usage of file module

The file module does not copy a file from src to dest.  This change
uses rsync to do so, registering a change only when rsync actually
syncs the file.

We also fix some incorrect references to what should be
{{ system_user }}.
