This change adds properties to v2.1
os-extended-server-properties and os-extended-volumes nova APIs
in order to expose information which is required for the standalone
EC2 API implementation (resides on stackforge/ec2-api) to use only
public APIs. Right now this information is taken by directly accessing
internal Nova DB.
It adds proposed microversion v2.3.
It implements the spec "Nova changes required for standalone EC2 API
implementation" in this review: https://review.openstack.org/#/c/153636/

Implements: blueprint ec2-api
