v0.48.0

feat: Add `data_tiering_enabled` @Cheezmeister (#175)

what

• Introduce var.data_tiering_enabled and plumb it through to the aws provider

why

• @teikametrics needs to set data_tiering_enabled true to provision our desired node type

  Error: error creating ElastiCache Replication Group (bidder-redis-cluster-production): InvalidParameterCombination: When     using the cache.r6gd.xlarge node type, you must enable data tiering.
  status code: 400, request id: REDACTED
  

• This flag data_tiering_enabled doesn't currently exist in the terraform-aws-elasticache-redis module
