      Work Description: jack-moseley opened a new pull request #3306:
URL: https://github.com/apache/gobblin/pull/3306


   Dear Gobblin maintainers,
   
   Please accept this PR. I understand that it will not be reviewed until I have checked off all the steps below!
   
   
   ### JIRA
   - [x] My PR addresses the following [Gobblin JIRA](https://issues.apache.org/jira/browse/GOBBLIN/) issues and references them in the PR title. For example, "[GOBBLIN-XXX] My Gobblin PR"
       - https://issues.apache.org/jira/browse/GOBBLIN-1466
   
   
   ### Description
   - [x] Here are some details about my PR, including screenshots (if applicable):
   Each of the `DagManagerThread`s had its own meter (but with the same names) previously, which causing confusing results when reading them, instead there should only be meters shared across the threads.
   
   - For service level meter, created one meter in the `DagManager` and passed it to each thread instead
   - For group level meters, created a static map keyed by group name to be shared by all threads
   
   ### Tests
   - [x] My PR adds the following unit tests __OR__ does not need testing for this extremely good reason:
   Tested locally by printing meter values in each thread
   
   ### Commits
   - [x] My commits all reference JIRA issues in their subject lines, and I have squashed multiple commits if they address the same issue. In addition, my commits follow the guidelines from "[How to write a good git commit message](http://chris.beams.io/posts/git-commit/)":
       1. Subject is separated from body by a blank line
       2. Subject is limited to 50 characters
       3. Subject does not end with a period
       4. Subject uses the imperative mood ("add", not "adding")
       5. Body wraps at 72 characters
       6. Body explains "what" and "why", not "how"
