Split up issue in two steps

• First part developing the code and demo
• Testing part will have to wait till team has correct credentials and we have a test environment

acceptance criteria:

Scenario: Valid Kinesis steam

Given: Config file has a valid Kinesis stream
When: an Operator executes the app
Then: CNM messages will be posted (how can this be validated?)

Scenario: non Valid Kinesis steam

Given: Config file has a non valid Kinesis stream
When: an Operator executes the app
Then: App will return an error message

@eigenbeam A reminder (mostly for myself, since I managed to forget about it): We have https://github.com/nsidc/cumulus-publish-cnm This is your chance to decide whether we mess with it or make something fresh!
