Summary: We want to rename away from "mercurial". Rather than rename the "mercurial" Python package, we opted to just collapse it into the parent "edenscm" package. This is also a step towards further organizing we want to do around the new project name. To ease the transition wrt hotfixes, we now replace "edenscm.mercurial" with "mercurial" to fix imports within base64-python extensions.
