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.
