PR Process

• Add pull request template, including a checklist for testing
• Add a semantic conventional commit check for PR titles (for creating the changelog for releases)

Pipeline

• Split pipeline into two stages: Build (images and charts) and Deploy (on CI/CD clusters)
• Add an environment lock to the Deploy stage so that only one merge to main can acquire that lock at a time
• Add running the TestKube tests on the CI/CD clusters to the Deploy stage, so that a new version cannot be deployed on the CI/CD clusters until the current tests have finished running

Docs

• Add a testing README for processes, Ginkgo and TestKube info, how to run the tests and bootstrap clusters, how to add new tests, etc.

Tests

• Add the otelcollector/tests folder that has the starting e2e tests, split up into test suites
