Tfhartmann/plat 2103 send ecs cluster data to cloudwatch (#2)

* Adding Script to send metrics into cloudwatch

* Update to ECS Cluster Service

to add a job to send metrics to cloudwatch

* Updated command

Included timestamp

* Added Unit and more Dimensions

* Adding instance ID

* Adding some logging

Also changing up what the metric is by removing dimensions

* Change to count registered instances

* comment out unused var

Since we aren't using that var at the moment, I commented it out, this
should also make the runtime faster

* Adding CODEOWNERS File

* Oh... I'm going to feel so dumb.

* Adding back ContainerInstancesCount
