release: published 5.13.1

### 5.13.1 (2019-10-10):

- utilization/common.request() function now listens for an agent
  restart/disconnected event
  - multiple agent restarts caused the number of 'stopped' listeners to exceed
  listener limit

* Added back generation of entity stats logging and uninstrumented support metric
  generation on metric harvests.

* Fixed inconsistent async return from collector API. This could result in an
  infinite loop due to attempting to merge before clearing. *This bug should not
  have impacted normal agent runs but was uncovered for certain test cases.*

* Removed legacy harvest code from main agent.

* Updated  to v3.

 Shoutouts to @asturur for the contribution.

* Added diagnostic code injector.

  The agent may now be configured to make transaction state checks via code
  injection. This may be turned on by setting
  to . While this option is enabled, code around async boundaries will be added
  to track transactions, and log a message when they are not properly reinstated.

* Fixed bug where  would not properly harvest when configured to.

*  now defaults to 'Unknown' in serverless mode to allow
  Distributed Tracing to function correctly when is not defined.

* Upgrades  to latest version

* Bumps  to latest version.

* Fixes tests that leave work scheduled on the event loop.

* Adds  flag to mocha test runs to prevent infinite runs on CI.

* Fixed issue that could result in vendor utilization detection failure.
  As a part of this fix, the request that hits the timeout will immediately abort
  instead of hanging around for the default timeout.
