Description of the issue

We added the awsentity processor to the container insights pipeline including the add_entity flag for the emfexporter.

This causes a problem where the entity processor tries to get the service name and now it overrides the EMF log's Service field which is unintended. This creates the wrong metric dimension and high cardinality metrics.

Bad: "Service": "busybox-service-jn9tc"
Good: "Service": "busybox-service"

Description of changes

Add an allow list to the awsentity processor to only allow entity attributes to be appended to the telemetry. For container insights we will only append the platform type:

"com.amazonaws.cloudwatch.entity.internal.platform.type"
