WHAT
Test F03 is failing as it was written with STS in mind but not tested on non-STS.

Make CRO add tags to replication groups for non-sts clusters.

STS clusters tag the elasticache resources on creation, but non-STS tag the nodes only.

See here: https://github.com/integr8ly/cloud-resource-operator/blob/master/pkg/providers/aws/provider_redis.go#L349

HOW
Add tags to replication group - see AddTagsToResource function used in TagElasticacheNode

It might be possible to change the code to only tag the replication group, and not have to tag the nodes as the docs state that: "Tags will be added/removed from the replication group and the action will be propagated to all clusters in the replication group."

DONE
Elasticache replication groups have tags for non-STS clusters
 
F03 passes for a non-STS cluster
