[tests] Improve Cosmos EndToEnd test

[radical]

Wait for the texts indicating that the db, and service are ready for requests before sending the http request. This helps with unnecessary attempts, and wait times in the retry pipeline.

• [tests] TestProject.WorkerA - reduce pings logged to every 30s instead of 1s to reduce noise in the logs
• [tests] TestProject.AppHost - use single line logging to help with matching log texts in the tests
• [tests] EndToEnd tests - add some text to wait for before sending the http request

What do you think about removing this test from the EndToEnd and putting it in its own FunctionalTests? Like we did for the other integrations. I think this is just left over from that work.

Then we wouldn't need to clutter up the EndToEnd tests with this change.

Makes sense. cc @sebastienros as he has been adding the functional tests.

Added cosmos to #4741 . Closing this in favor of that issue.
