Remove NewRelic instrumentation

[johnpaulashenfelter]

With DataDog on the horizon and with NewRelic no longer offering us even the free tier of service, its time to remove the bits and pieces of code added to support the NewRelic integration:

Vets-api

• [x] NewRelic gem department-of-veterans-affairs/vets-api#4484
• [x] newrelic.yml file department-of-veterans-affairs/vets-api#4484

Devops

• [x] Deploy configuration for staging (devops repo) department-of-veterans-affairs/devops#7217
• [x] Deploy configuration for production (devops repo) department-of-veterans-affairs/devops#7217
• [x] credstash license removal

Config

• [x] Disable NewRelic account

$ credstash delete vets_api.newrelic.license Deleting vets_api.newrelic.license -- version 0000000000000000001 $ credstash get vets_api.newrelic.license Item {'name': 'vets_api.newrelic.license'} couldn't be found.
