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

Custom resource detectors related to generic platforms (e.g. Docker, Kubernetes) or vendor specific environments (e.g. EKS, AKS, GKE) MUST be implemented as packages separate from the SDK.

We have Host, OS, Process, and ProcessRuntime detectors in the sdk-common module. AWS and GCP belong to separate modules.
