This patch does the following:
1. Added the apps role so that k8s app deployment can be placed in the role
2. Added cockroachdb-init-pod deployment inthe post role since this has to
be deployed first.
3. Added cockroachdb-pod deployment in the apps role
4. Allow this workload to stand up a standalone cockroachdb cluster or
join in an existing cockroachdb cluster
5. Added the cockroachdb load generator container so that once the cluster
is started, there will be some load generated.
6. Added a way to pre-allocating floating IP addresses so that the workload
can use pre-allocated floating IPs for VMs.
