Remove airship-citycloud nodepool provider

Once we've settled on a max-servers value of 0 without any servers this
is the nextstep in removing the provider. This should completely remove
the provider from the launcher and the image builders.

We keep the airship-citycloud nodepool provider for historical
information purposes. We can clean this up later.
