Node.js agent v9.15.0

Notes

• Added a new configuration option heroku.use_dyno_names to specify whether or not to use process.env.DYNO for naming the host name and display host. This option defaults to true. If you are on heroku and do not want this functionality set heroku.use_dyno_names to false. You can also control this configuration options with the environment variable of NEW_RELIC_HEROKU_USE_DYNO_NAMES. Thanks @benney-au-le for your contribution 🚀

Support statement:

• New Relic recommends that you upgrade the agent regularly to ensure that you're getting the latest features and performance benefits. Additionally, older releases will no longer be supported when they reach end-of-life.
