Upgrading to 0.37.0

This release introduces mainly bug fixes as well as some new configuration options for the profiling library.

Profiler

New environment variables have been added to allow you to easily configure and describe your application in Datadog.

• DD_SITE: Specify which site to use for uploading profiles. Set to datadoghq.eu to use EU site.
• DD_API_KEY: an alias to DD_PROFILING_API_KEY.
• DD_ENV: the environment in which your application is running. eg: prod, staging
• DD_VERSION: the version of your application. eg: 1.2.3, 6c44da2, 2020.02.13
• DD_SERVICE: the service which your application represents.
