Add horizon checks to maas_local.yml

We're currently only monitoring horizon remotely (via VIP endpoint),
this change creates individual checks so we can identify when
individual horizon nodes go down.

Add nova-cert check

This adds a check / alarm to maas_local for nova-cert.  We use the
nova_service_check.py plugin and as long as the nova-cert is running
then we'll have entries in the nova service list output for nova-cert.
Add check/alarm for neutron-metering-agent
fixed bug, thanks @jwagner

Separate out the Cloud Files tenant_id and regular Cloud tenant_id

Cloud Files uses the MossoFS tenant, this is not the same as the
tenant_id used for authenticating with Rackspace Cloud.

* Separate out the 2 settings in user_variables to ensure these are
  noted as being different values.

Fixes #103
Adjust the user variables location for the maassetup.sh script

Allow instance resize on same host

In v4.2.x, allow_resize_to_same_host defaults to True so that in resource
constrained installations, a resize can happen on the existing host if
there are enough resources there to do it.

- Change allow_resize_to_same_host to True to prevent resize regression in
  9.0.0

Fixes rcbops/ansible-lxc-rpc#104
