Fail if autidisk_size is less than 10GB

The disk size must be at least 10GB for ceph to work smoothly.
The reasons for minimum 10GB are:

* Ceph OSD journal need at least 2GB, otherwise journal creation fail
* OSD need at least 7-8GB to hold default and pools for openstack,
    otherwise data write to the pools will fail.
Support ceph storage cluster less than 3 nodes

By default ceph cluster need at least three nodes to be in the
cluster to store data in it, as default number of object replicas
is 3.
Adding a parameter to change number of object replicas of all pools,
so that anyone need less than 3 nodes in cluster can specify appropriate
replication factor (1 or 2) to make the cluster up.
Update roles in site manifest

1. remove roles that we are not going to deploy.

We have plenty of roles to maintain without making up new ones.

2. don't deploy ceph profiles on controllers

b/c it doesn't work yet

3. add the actual storage roles

- st (osd only)
- stmon (osd + mon)
- stmonleader (osd + mon leader)

Don't anchor end of hostnames

Because they might end with a project id.
Fix issue with pull request merging

Previously, the merge of puppet requests was failing.

This commit ensures that a valid user/email is configured
and that pull request merging is non-interactive.

Let's all use the same environment
Add Glance to consul
Use consul names by default and let envs override
Remove superfluous overrides from hiera

Add a production.yaml to show what sort of stuff /should/ be overridden.
remove all traces of dan env

It was a temporary thing used for testing that does not
need to exist anymore
Update rjil::keystone::public_address

It was set to the load balancer address, but it is actually
the bind address that local keystone services are bound to.

I updated the default to set it to 0.0.0.0 and added the env
specific overrides.
Added bind_addr param to consul classes

Previously it only worked if you wanted to bind
it to eth0 (or whatever happens to be the first
interface).

This patch adds a param to all consul classes so
that it can be set.

It also adds hiera data to set it for virtual-box.
Add service blocker

Adds the service blocker class which blocks catalog application
until the specified service name resolves to at least one address.

This is intended to block parts of the catalog on external
dependencies.
Ensure that consul refreshed before we start blocking

To avoid deadlock.
