API version history:
1.0 - Initial version.
1.1 - Added get_backdoor_port()

existing methods in 1.x after that point should be done such that they
can handle the version_cap being set to 1.1.
2.0 - Major API rev for Icehouse
... Icehouse, Juno, Kilo, Liberty, Mitaka, Newton, and Ocata support
message version 2.0. So, any changes to existing methods in 2.x after
that point should be done such that they can handle the version_cap
being set to 2.0.
