- Remove default value for openshift_hostname and make it required
- Remove workarounds that are no longer needed
- Remove resources parameter from openshift_register_node module
- pre-create node certificates for each node before registering node
- distribute created node certificates to each node
- Move node registration logic to a new openshift_register_nodes role
  - This is because we now have to run the steps on a master as opposed to on
    the nodes like we were previously doing.
- Rename openshift_register_node module to kubernetes_register_node, one more
  step to genericizing enough for upstreaming, however there are still plenty
  of openshift specific commands that still need to be genericized.

- Set --hostname flag in node config in openshift_node role
- Support some additional node attributes in openshift_node role
  - podCIDR
  - labels
  - annotations
- Support both output types for openshift ex config view in
  openshift_register_node module
- Support multiple api versions in openshift_register_node module
- Support additional attributes in openshift_register_node module
  - annotations
  - labels
  - pod_cidr
  - external_ips (v1beta3, will be available after next kube rebase)
  - internal_ips (v1beta3, will be available after next kube rebase)
  - hostnames (v1beta3, will be available after next kube rebase)
  - external_id (v1beta3, will be available after next kube rebase)

- Set parameters resources and cpu/memory as mutually exclusive
- Add parameters for setting the client_user, client_context and client_cluster
  - This allows the module to ensure it is using the proper context for operation
- Node resources weren't properly being registered
  - wrapped node definition object in a config object to rectify
- Reduce default to 75% Total Memory instead of 80%
- Don't bother running osc create node if node is already in osc get nodes
  output

- add openshift_register_node module to openshift_node role
  - verifies that node isn't already registered before attempting to register it
