Loki Storage Logic needs exception for MinIO
Currently, the loki storage configuration refers s3 if loki deployment type != Monolith even if s3 isn't the intended endpoint (i.e. not filled), causing an error. This needs to be fixed. See current logic https://repo1.dso.mil/big-bang/bigbang/-/blob/master/chart/templates/loki/values.yaml?ref_type=heads#L81
