Support Cortex metrics provider in Keptn Metrics Operator

[odubajDT]

Goal

Support Cortex metrics provider as Keptn Metrics Provider.

Details

Cortex implements the Prometheus HTTP API to query data via PromQL. Therefore it is possible to use the current implementation of Prometheus provider and introduce an integration with Cortex.

DoD

• use the already implemented Prometheus provider and adapt the provider.go to support Cortex
• unit tests
• document new provider usage
