Remove obsolete redhat-eventlet.patch

See I62ce43a330d7ae94eda4c7498782a655e63747fa for the gorey details on
why this exists.

As of this fix:

https://github.com/eventlet/eventlet/pull/34

which was released in eventlet 0.13, we no longer need the patch.

This has now been removed from oslo-incubator, so this is really just
syncing that removal.

Add boto special casing for param changes in 2.14

boto 2.14 has some interface changes with the get_http_connection
call which adds port as a non optional parameter *in the middle of*
existing non optional parameters. It's a special kind of incompatible
change.

We are already special casing around boto in the unit tests, lets
just do more of that if we are running on a newer version.
