Description of problem:

As seen in RHODS-7769, rhods-prometheus-operator requests 600m of memory. I believe this should be 600MiB instead, according to the kubernetes docs: 

Pay attention to the case of the suffixes. If you request 400m of memory, this is a request for 0.4 bytes. Someone who types that probably meant to ask for 400 mebibytes (400Mi) or 400 megabytes (400M).

Having a low memory request could make the pod to be evicted if the cluster has low resources

Steps to Reproduce

1. Install RHODS 1.25 RC Build
2. Check memory requests for rhods-prometheus-operator

Reproducibility (Always/Intermittent/Only Once):

Always

RHODS 1.25 RC Build (April4, 470473)
