This adds the 2.37 microversion to the REST API for automatically
allocating a network, i.e. get me a network.
The majority of the changes to the REST API concern request
validation. 'networks' is now required in the server POST body
after this microversion. The 'auto' or 'none' special network
uuid values are used, but if specified, can not be specified
with any other requested network values.
The other special case that is checked is when the minimum
compute service version is not new enough to support this change,
i.e. a Mitaka compute will not have the network API code that
knows how to deal with the special auto/none network IDs. Because
the REST API is checking the service version, the service caches
the service version after the first check. Once all computes are
updated to Newton then a restart of the nova-api service(s) will
be required to flush the cache. A release note is provided for
this situation.
The api-ref docs are also updated for this microversion including
an example API sample request.
