The rbt setup-repo command will now set the REPOSITORY_TYPE key in

.reviewboardrc. These tools are looked up by entry point name, which

does not necessarily line up with the tool's name (i.e.,

SCMClient.name). As such, we now save the entry point name when

loading tools so we can refer to it.

Ran rbt setup-repo and saw that the REPOSITORY_TYPE key was

included.
