local-up-cluster additions

**What this PR does / why we need it**:
Changes to local-cluster-up: These include: 1)  a simple additional help option. 2) additional error message to not being able to run `docker ps`. 3) fail faster when etcd is not found in path. Hopefully these make developing a bit more pleasant.

**Release note**:
```NONE
