ResourceDetectors - Process

[Kielek]

Fixes N/A.

Changes

Initial implementation for process.pid detector from https://github.com/open-telemetry/semantic-conventions/blob/main/docs/resource/process.md#process (this attribute is what I need for now).

The plan is to release shortly as alpha with reference to OTel 1.6.0.
Then create follow up help-wanted issue to extend it for another attributes and update OTel to 1.7.0.

For significant contributions please make sure you have completed the following items:

• Appropriate CHANGELOG.md updated for non-trivial changes
• [ ] Design discussion issue #
• Changes in public API reviewed

Notes

Previous initial implementation of resource detector: #1449
You can expect one more similar, for https://github.com/open-telemetry/semantic-conventions/blob/main/docs/resource/host.md, espiecially host.name.

Will do, just after initial release.
