Background
Implement metrics for monitoring block upload operations.
Discuss as a group what type of Metric to use prior to implementing this issue.

See https://github.com/hashgraph/hedera-services/blob/16770-block-stream-bucket-uploader-design/hedera-node/docs/proposals/block-stream-bucket-uploader.md#configuration-classes for more details.

Look at OpWorkflowMetrics as an example for more information.
See FunctionGauge as well.

Acceptance Criteria

• Metrics for the following
  • Number of files on the filesystem (root block file directory, uploaded directory, hashmismatch directory)
  • Latest/Avg latency for uploads to each bucket
  • Error codes on upload to each provider
  • Count of successful uploads to each provider
