* 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.
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.
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.
