As nova-spec api-microversions, versions API needs to expose minimum
and maximum microversions to version API, because clients need to
know available microversions through the API. That is very important
for the interoperability.
This patch adds these versions as the nova-spec mentioned.
Note:
As v2(not v2.1) API change manner, we have added new extensions if
changing API. However, this patch doesn't add a new extension even
if adding new parameters "version" and "min_version" because version
API is independent from both v2 and v2.1 APIs.
