SDK: environment-aware TelemetryResource

[iRevive]

OpenTelemetry Java can detect a large variety of environments (e.g. GCP, AWS ECS, etc) and add additional environment-specific attributes to the TelemetryResource. For example, when an application runs in the container, the container.id attribute can be added to the telemetry resource.

We can implement the following: a) Common: Container, Host, OS, Process b) Google Cloud: GCP c) AWS: Beanstalk, EC2, ECS, EKS, Lambda
