Add a pkg for iptables support

This makes iptables an injectable dependency.  The test for this started off
simple, but got a bit out of hand.  It's starting to become a mocking

Allow etcd config file to be passed to apiserver, kubelet, and proxy
Make ResourceVersion a string internally instead of uint64

Allows us to define different watch versioning regimes in the future
as well as to encode information with the resource version.

This changes /watch/resources?resourceVersion=3 to start the watch at
4 instead of 3, which means clients can read a resource version and
then send it back to the server. Clients should no longer do math on
resource versions.
Change test cases to verify the client sends the received resourceVersion
