Travis Nielsen 1afd322650 core: ensure cluster name is available on cluster info
The cluster info is important context for the cluster controller to
create the cluster, and all the fields must be properly set.
A test cluster name was being set temporarily, resulting in
mons incorrectly getting the wrong cluster CR name. There is no
known issue from the temporary value, it was just exposed by
https://github.com/rook/rook/pull/8678 setting the value to a label.

Now the functions are more clearly named so only unit and
integration tests should be using the test value for the cluster
name where it is not important.
