* Moving from govendor to dep.
* Making the pull request template more friendly.
* Fixing akward space in PR template.
* goimports run on whole project using ` goimports -w $(find . -type f -name '*.go' -not -path "./vendor/*" -not -path "./gen-go/*")`
source of command: https://gist.github.com/bgentry/fd1ffef7dbde01857f66
* fixed semantics. Earlier mentioned that 'Pystachio does yet support...'. Changed now to mention 'Pystachio does not yet support...'
* fixed grammatical mistake.
* Ran gofmt on project.
* Code cleanup: Deleted multiple functions which have become stale. Removed cluster example as we replaced the need to create the Cluster object.
* Cleaned up ZK connection code by using the backoff function. Added a test to the end to end to test that we're getting the host correctly from ZK. Changed clusters test to be an outside package.
* Added LeaderFromZKURL test to end to end tests.
* Added logger to realisConfig so that users can attach their own Loggers to the client. Logger is an interface that shadows most popular logging libraries. Only Print, Println, and Printf are needed to be a realis.Logger type. Example in the client uses the std library log.
* Moved most fmt.Print* calls to be redirected to user provided logger. Logger by default is a no-op logger.
* Adding CreateService to realis interface. Uses the StartJobUpdate API to create services instead of the createJobs API.
* Bumping up version number inside client in anticipation of new release.
Added new monitors for watching number of instances get to a certain count using polling.
Added new commands to sample client which give some statistics.
Added the ability to kill and restart specific instances.
Fixed incorrect documentation on using-the-sample-client.
Added helper functions under the response package to extract fields from
aurora.Response.
Some tests included for making sure the JSON blob pulled from Zookeeper
is correct.
Updated client to be able to take Zookeeper json cluster config that is
currently being used in aurora (clusters.json usually located at
/etc/aurora/cluster.json).
Changed error messages to no longer have a period at the end as that was
throwing off printing of the error.
Modified samuel's ZK library slightly to stop verbose logging using a
NoOpLogger from stackoverflow.
