newrelic 8.1.0

v8.1.0

on Node.js Yarn

Added necessary instrumentation to support v4 of mongodb.

• Explicitly enabled APM for mongodb instrumentation(client.monitorCommands = true)

Fixed issue where Promise based pg.Client.query timings were always in sub-millisecond range.

Fixed bug where API.shutdown would not harvest or keep process active effectively after an agent restart.

The agent will now correctly update its state to 'started' after a reconnect has completed.

Added an eslint rule to verify every file includes the copyright statement.

Fixed the homepage field in package.json to use https in the link to the github repo. Thank you @pzrq for the contribution.
