Give a prospective removal date for all v2 APIs

All the v2 APIs are marked as deprecated, but the v2_auth and v2_ec2
did not have proposed removal dates. In keeping with the general
standards, the earliest we can do this is Pike + 4, although we
specify this as Mitaka + 7 so as not to change the actual release
version we first marked these as deprecated.

+    The v2.0 ``auth`` and ``ec2`` APIs were already maked as deprecated in the Mitaka release,
+    although no removal release had yet been identified. These APIs will now be removed in the 'T' release.
+    The v3 APIs should be used instead.
