[Change Request] Minor bodhi update

[Luke Macken]

Hi guys,

I'd like to do a low-risk bodhi upgrade this weekend.  Changes include:

  * A new argument to the 'list' API method that will be utilized by
    Fedora Community.  This does not break the existing API.
  * Added FormEncode validators to the 'list' API method, which fixes a
    couple of issues, and ensures we get the data that we expect.
  * Made some parts of the updates push process a bit more robust, so if
    there is a problem with 1 update, it won't effect the others.  This
    will help us mitigate some recent explosions that we saw due to
    race-conditions.
  * Fixed some Koji session issues, which we have been hitting
    every now and then during pushes.
