v1: Make mepo status serial

This is a release of mepo v1. It changes mepo status to be a serial command rather than using multiprocessing. It was found at NAS that mepo status was acting fork-bomb-like spawning many, many processes. This isn't really needed anyway for status so we make it serial based on code in mepo v2
