Add new relic notification script post deploy. (#27)

* Add new relic notification script post deploy.

* Review fixes:

- Consolidate kubectl commands
- Get actual API key
- Update jsonpath to image to be more specific

* Review fixes #2:

- Use regex to get image hash from yaml (instead of asking k8s)
- Alphabetize some things

* Review fixes part 3:

- Wrap subshell command to capture output
- Improve comments
- Notify new relic prior to waiting for/running acceptance tests
