* Added sysObjectID test for olts.
* Commit to trigger travis-ci
* Update fiberhome.yaml
* refactor: OS discovery tests are now dynamic
All that needs to be done now is supply snmprec files with the proper name. os.snmprec or os_description.snmprec
I also tweaked the loading of yaml files to speed up the tests substantially.
Verifies all os have at least one test and all snmprec files are tested.
* fix typo
