Crash for "cm get cc"

[KevinFCormier]

I created a ClusterClaim from a ClusterPool with size 0 using cm-cli. I did not change the size of the pool and allowed the command to run to failure.

Afterwards, cm get cc crashes:

% cm get cc
panic: runtime error: index out of range [5] with length 5

Here is the output from ck:

The ClusterClaim I created was test.

Update help text for "create cph" (#71)

create cph takes an argument of `--api-server` but the help text example uses `--apiserver-url` leading to the following error:
```
$ cm create cph <clusterpoolhost-name> --apiserver-url <api-url> --console <console-url> --group=<group> --namespace=<namespace>
Error: unknown flag: --apiserver-url
```
