WHAT
We need to ensure that all of the containers running on pods related to RHOAM installation have their requests set for CPU and memory. For the majority of these containers, we are not hardcoding values however we will for the envoy sidecar containers. Additionally we need an e2e test to confirm these values are actually being set.

HOW
This PR can be used to implement the requests: https://github.com/integr8ly/integreatly-operator/pull/2651/files
This PR can be used to start off with the e2e test: https://github.com/integr8ly/integreatly-operator/commit/057c0511a69a691bfb66fe274b2053816ce46683

TESTS
e2e and unit tests where required

DONE

• The envoy sidecar containers' requests for CPU and memory are set
• Added an e2e test that verifies that the containers with hardcoded request values are properly configured
