Adds indexer level task metrics <!-- Replace XXXX with the id of the issue fixed in this PR. Remove this section if there is no corresponding issue. Don't reference the issue in the title of this pull-request. --> <!-- If you are a committer, follow the PR action item checklist for committers: https://github.com/apache/druid/blob/master/dev/committer-instructions.md#pr-and-issue-action-item-checklist-for-committers. --> ### Description This PR adds indexer level task metrics- ``` "worker/task/running/count" "worker/task/assigned/count" "worker/task/completed/count" ``` These metrics will provide more visibility into the tasks distribution across indexers (We often see a task skew issue across indexers and with this issue it would be easier to catch the imbalance) <!-- Describe the goal of this PR, what problem are you fixing. If there is a corresponding issue (referenced above), it's not necessary to repeat the description here, however, you may choose to keep one summary sentence. --> <!-- Describe your patch: what did you change in code? How did you fix the problem? --> <!-- If there are several relatively logically separate changes in this PR, create a mini-section for each of them.
