Release 0.6.1 to patch influxdb driver issue.
Refactoring and fixes of /docker API endpoint.

This canges the output of the Docker endpoint to be a map so that it is
more consistent from single to multiple returns. It also refactors
internally how we handle both types of requests.

Without this PR the /docker API endpoint is broken completely so this
change in format has no effect anyways.

These changes are tested by the upcoming integration tests.

Refactoring and fixes of /docker API endpoint.
Adding integration test framework along with 3 tests.

These tests are similar to Go unit tests except that they're targetting
tesing of a running cAdvisor client. They do this by interacting with
the testing framework that is able to talk to the running cAdvisor. This
cAdvisor could be local or remote.
