Swift: Set Content-Length when requesting/checking Keystone tokens

Running Keystone with WSGIChunkedRequest=On is not supported.

We have to make sure that we set the Content-Length header when getting
an admin token and checking revoked tokens, otherwise Keystone returns
a HTTP 411 error.

Same applies when checking revoked tickets.
