Support all API versions up to 1.latest

Only 1.11 is a breaking change, and it's needed to support ENROLL state
in python-tripleoclient. Adding support for all recent versions was no
harder than adding support for one, since the version number is passed
uninspected to the internal HTTP client in all cases.

API versions 1.1--1.4 and 1.7--1.8 were previously unsupported, despite
higher versions being supported. I couldn't see any reason for this
(there are tests in the main Ironic codebase for the use of those minor
versions), so I added those in too.

The file ironicclient/osc/client.py seemed to just duplicate code from
openstackclient.common.utils and add an extra level of indirection
without providing any benefit. It also required the list of supported
APIs to be maintained in two places, so rather than duplicate my changes
I've removed it.
