openstack/nova - nova - OpenDev: Free Software Needs Free Tools

The api documentation is now published on docs.openstack.org instead
of developer.openstack.org. Update all links that are changed to the
new location.
Note that Neutron publishes to api-ref/network, not networking anymore.
Note that redirects will be set up as well but let's point now to the
new location.

Due to the migration of the OpenStack document library, some outdated
links were found during use, using https instead of http and pointing
to the right place.

Rate limit is not support in v2.1 API any more, update doc to
remove that part.
Change-Id: I57742c10c6a6ad97f400db3c928fccf3d8f4733c

The endpoint of v2.1 API is CURRENT now.
On v2.1 API, a tenant-id is not necessary to be specified on the
URL, that is good for making API calls simple for users.
In addition, the endpoint is different from old v2.0 API.
Then this patch makes the api-site fit for v2.1 format.
Partially implements blueprint api-ref-in-rst
