most spark conf keys are case sensitive, including
`spark.blockManager.port`, we can not get the correct port number with
`spark.blockmanager.port`.
This PR changes the wrong key to `spark.blockManager.port` in
`BasicExecutorFeatureStep`.
This PR also ensures a fast fail when the port value is invalid for executor
containers. When 0 is specified(it is valid as random port, but invalid as a
k8s request), it should not be put in the `containerPort` field of executor pod
desc. We do not expect executor pods to continuously fail to create because of
invalid requests.
### Why are the changes needed?
