Public bug reported:

If a gabbi file sets a default microversion by setting a header
'OpenStack-API-Version' with a value like 'placement latest' and then
later overrides that in an individual test with a header of 'openstack-
api-version' the difference in case can lead to failure.

In the best case the failure is consistent.

In the worst case it can sometimes work, because the header shows up
twice in the request, and the last header wins.

The solution is to always use the same case through the file.

Note that gabbi is case sensitive here in part because of the
implementation but also because it provides control and possibility to
test exactly this problem.
