Allows client libraries to have complete access to the rest of the OSC ClientManager. In addition, extension libraries can define global options (for API version options/env vars) and define versioned API entry points similar to the in-repo commands. The changes to ClientManager exposed some issues in the existing object api tests that needed to be cleaned up. Change-Id: Ic9662edf34c5dd130a2f1a69d2454adefc1f8a95
