Simplify deployment in federation CI jobs
**What this PR does / why we need it**:
Introduce a new variable `USE_PV_FOR_ETCD` to control whether to use PV for federation etcd. `USE_PV_FOR_ETCD` is set to false by default and can be overridden in CI jobs where we want to test with PV. For most of the federation CI jobs, it does not matter whether we use PV for etcd or not. We can overcome some issues by not depending on PV's in federation setup like failure to bind to PV and leaking PD's. etc...
#50543 is one such issue associated with PV.
This PR also contain a commit to fix couple of minor issues and removing unnecessary include of cluster/common script.
**Release note**:
```release-note
NONE
