Code Issues Proposed changes

Scheduler rpcapi 2.9 is not backwards compatible

Browse Source 
Patch 552693e4ad51291c8bfd28cd1939ed3609f6eeac which added scheduler
rpcapi version 2.9 does not provide any backwards compatibility.

This patch adds the check using 'self.can_send_version', and falls
back to the latest Grizzly compatible version if it the version is
capped.

Also takes the opportunity to make the docstring more consistent in the
scheduler rpcapi SchedulerAPI class.

Closes-bug: #1220112
