[CLIENT-3186] CI/CD: Use entrypoint script to finish setting up strong consistency instead of the run-ee-server composite action

[juliannguyen4]

Extra changes:

• Add healthcheck to check that container is ready to use through Github Actions or locally on the command line
• CI/CD: wait-for-as-server-to-start composite action now fails if we cannot confirm that the server is ready to use for testing within 30 seconds
