Initial creation of a combined rackspace auth identity filter

Along the lines of ip-identity, but specifically for rackspace's auth
token posting logic.
Implemented json and XML parsing of the payloads to get back usernames

There are tests for the payloads that I can think of we could possibly
want to rate limit on.

I think we'll need better requirements regarding how to handle the
myriad ways to authenticate in v2.0
Got a couple simple unit tests passing.

Managed to avoid mocking most of the world.

Now lets go theif some integration tests.
Adding it to the filter-bundle

Eventually, it should go somewhere external
Actually do the quality setting correctly. Sneaky Sneaky java methods
Add a couple rackspace auth identity tests

It could use a lot more, but the filter works :D
Yep, my stuff is in maven central
Removing the dependency management dumbness
Better named function
So only release 3.4.0-M1 is on maven central
A bit of clean up, and handling the LimitedRead thingy like it's handled
elsewhere

I don't really like this thing, but it's used elsewhere, and it's
behavior is tested...

It required that I delete the "integration" test I was using for the
filter, because the input stream cannot be reset :(
Took out mockrunner, because it's not useful
Tweaks to make it work
Missed something
update test to include test for v1.1 and v2.0, also rename test to fix for both versions
update test -remove test for passwordCred and other v1.1 internal contracts
Modified the test a bit

Cleaned up things, made sure it submitted POSTS for real.

Added a couple tests that ensure it doesn't break on non-post
requests.
Only do stuff if it's a POST
make the package name all lower case
Added POST request test with random data
