Minimal implementation of the ranged (=threaded) segment loop service, to improve performance over the existing loop. Has tests with a an inmemory segment database and example observer. Does not have yet: database link, observer duration tracking, suspicious processed ratio guard, rate limiting, minimum execution interval per observer, etc. Part of https://github.com/storj/storj/issues/5223 Change-Id: I08ffb392c3539e380f4e7b4f1afd56c4c394668d
