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. Closes-Bug: #1443375 Change-Id: Id464a07d624d0e228fe0aa66a04c8e51f292ba0c
