Users management recipe does not manage tags

[tophercullen]

For the default users recipe, tag management appears to be the only user attribute not actively managed by the default user management recipe. The 'set-tags' is only called when the user is first created, or the password is change. Only changing an existing user's tags doesn't actually apply those tag changes.

This seems to be intentional, but its unclear to me why.

@tophercullen I don't know if it's intentional but it can be revisited. Please submit a PR that demonstrates what you'd do?

This is what I mean by intentional https://github.com/rabbitmq/chef-cookbook/blob/v5.x/recipes/users.rb#L38

The PR is simple, I don't mind submitting it. I just didn't want to take the time to do so, if there's a specific reason its written this way.
