Support for build-time versions in pyVmomi

Since introduction of meta-versions and related
generated versions, we need facility, allowing
code to specify those versions during run-time.

(Note that although version classes are well-
defined, the particular versions that correspond
to a class change from build to build, depending
on meta-version state.)
