cephadm: tests - updated to include cephadm-exporter
Main unit tests now includes daemon and service
deployments for cephadm-exporter.
In addition, the assert_rm_daemon function has been
tweaked, to avoid problems with services that contain
'-' during fnmatch invocations. Service names that use
'-' could result in "bad character range" exceptions from
the re module, it can be treated like a range separator.
