[feature] Allow naming of Machine sets

[steverfrancis]

Problem Description

You can create a new worker machine set - but you are given no choice as to the name (at least in the UI) and are forced to accept a name like 'workers-4a7f5e' instead of 'workers-GPU' or something....

Solution

Allow the user to specify the name on creation, and optionally rename later.

Currently our resource names are also the IDs.

So one idea about naming resources (cluster, worker set etc.) is to go AWS way: human-readable names are just tags on the resources. We could do the same via annotations. That way we decouple the ID and the user-preferred name.

You can name them in the cluster templates. Just not in the UI.
