make scripts to manage creating and sshing to capi-workspace docker image on kubernetes

[sethboyles]

Currently, when trying out the docker image version of capi-workspace on kubernetes, we have to use some way to ssh to the pod. Typically we use k9s or kubectl.

I would be nice to have two commands:

1. something like create-capi-workspace that spins up a new pod and returns the (auto generated?) name of the pod.
2. something like capi-workspace <arg> that takes in the above name of a pod and sshs in for pairing.
