Nadav Har'El f1aaa91e21 merge: add metrics

Merged pull request https://github.com/scylladb/scylla/pull/6030 from
Piotr Dulikowski:

Adds CDC-related metrics.

Following counters are added, both for total and failed operations:

    Total number of CDC operations that did/did not perform splitting,
    Total number of CDC operations that touched a particular mutation part.
    Total number of preimage selects.

Fixes #6002.
Tests: unit(dev, debug)

* 'cdc-metrics' of github.com:piodul/scylla:
  storage_proxy: track CDC operations in LWT flow
  storage_proxy: track CDC operations in logged batches
  storage_proxy: track CDC operations in standard flow
  storage_proxy: add cdc tracker hooks to write response handlers
  storage_proxy: move "else if" remainder into "else" block
  cdc: create an operation_result_tracker object
  cdc: add an object for tracking progress of cdc mutations
  cdc: count touched mutation parts in transformer::transform
  cdc: track preimage selects in metrics
  cdc: register metric counters
  cdc: fix non-atomic updates in splitting
