    Make exception translation common and add to pecan

    This moves the exception translation logic from the
    legacy api.v2.resource module to a common module and
    re-uses it from pecan to bring consistency to the
    way language and exception translation is handled
    between the two.

    This also adjusts the policy enforcement hook to correctly
    handle the unsupported method case since 'after' hooks
    are executed after 'on_error' hooks that return an exception.
