Title: Add --only to `mb service *` and `mb environment configure`

Allow filtering nodes when running service commands (and also on
environment configure). This uses existing NodeFilter functionality.

Using a node filter on `mb environment configure` is considered an
anti-pattern, but there may be times it is necessary. The option is
hidden for that command, and is only intended to be used in unusual
situations (usually driven by automation).
