feat: switch to acm-metrics-2ti object storage

partly fixing nerc-project/operations#745

Update the configuration for ACM metrics object storage to use
- the acm-metrics-2ti.yaml file
- and the acm-metrics-2ti-object-storage name.

This new storage is for testing our problems with nooba, scaling storage pools, and ODF operator.
