Allow passing of version header

Add keyword option to get_version_data() to allow passing
of the version header so that we can get the microversions.
Specifically, this is so that we can re-use this function
in barbican, which recently implemented microversions, but
doesn't return them by default, for backward compatibility
with old clients.
