Perhaps API Versions should Match Easier

[Terry Howe]

If OS_IDENTITY_API_VERSION=2 is set, the v2.0 identity commands do not work. Perhaps API versions should be a little fuzzier on version matching.

This isn't going to be complete for m5, and we need to work out the normalization rules for versions yet.

    Liberalize version matching a bit

    For class-loading purposes we can just use the major version,
    so accept that. Only Identity and Compute were affected; Compute
    is included just to be pedantically complete.

    For command groups we also just use the major version so fix
    Compute and the version option handling.

    Change the internal default for Identity to a simple '2' so it
    is also consistent with the rest of the world.

    Then comes microversioning...
