consider shortening names for functions under internal/objects

[skriss]

Now that the helpers for different object types have each moved into their own package, some of the function names are redundant, e.g. clusterrole.EnsureClusterRole, clusterrole.CurrentClusterRole, etc. It'd help readability to simplify some of these names. Here's a quick PoC of what some shortened names could look like:

If folks think that pattern reads better, I can go through and make all the changes.

+1 fan of that pattern and reducing duplication

I agree that we should try and reduce stuttering when reading the actual call sites.
