operator: Add OpenShift CloudCredentials support for AWS STS

[JoaoBraveCoding]

What this PR does / why we need it:
The following PR adds auxiliary automation to reconcile the cloud credentials secret for OpenShift clusters installations on AWS using STS as the default method for cloud credentials. In detail the installation of the Loki Operator requires from the cluster administrator to provide a AWS Role ARN that will be used by the operands (i.e. Loki) to request short-lived token from STS to access S3. The enablement is based on the following OpenShift proposals:

• Tokenized Authentication for Red Hat Operators on Cloud Providers
• cluster-logging: Add LokiStack tokenized auth proposal openshift/enhancements#1503

Effectively the underlying implementation utilizes the CredentialsRequest using the Loki Operator AWS Role ARN to request the credentials secret from the OpenShift cloud-credentials-operator. It minimizes user input on object storage access for LokiStack installation to a list of buckets and an AWS region.
