KAFKA-13229: add total blocked time metric to streams (KIP-761) (apac…
…he#11149) * Add the following producer metrics: flush-time-total: cumulative sum of time elapsed during in flush. txn-init-time-total: cumulative sum of time elapsed during in initTransactions. txn-begin-time-total: cumulative sum of time elapsed during in beginTransaction. txn-send-offsets-time-total: cumulative sum of time elapsed during in sendOffsetsToTransaction. txn-commit-time-total: cumulative sum of time elapsed during in commitTransaction. txn-abort-time-total: cumulative sum of time elapsed during in abortTransaction. * Add the following consumer metrics: commited-time-total: cumulative sum of time elapsed during in committed. commit-sync-time-total: cumulative sum of time elapsed during in commitSync. * Add a total-blocked-time metric to streams that is the sum of: consumer’s io-waittime-total consumer’s iotime-total consumer’s committed-time-total consumer’s commit-sync-time-total restore consumer’s io-waittime-total restore consumer’s iotime-total admin client’s io-waittime-total admin client’s iotime-total producer’s bufferpool-wait-time-total producer's flush-time-total producer's txn-init-time-total producer's txn-begin-time-total producer's txn-send-offsets-time-total producer's txn-commit-time-total producer's txn-abort-time-total Reviewers: Bruno Cadonna <cadonna@confluent.io>, Guozhang Wang <wangguoz@gmail.com>
