[tor/master] test: Add v3 service config and registration test

commit 418059dd96f5f427eceffff1daeb2a2f6c4adbeb Author: David Goulet <dgoulet(a)torproject.org> Date: Tue Jan 17 12:09:54 2017 -0500 test: Add v3 service config and registration test This tests our hs_config.c API to properly load v3 services and register them to the global map. It does NOT test the service object validity, that will be the hs service unit test later on. At this commit, we have 100% code coverage of hs_config.c.
