Fix instance-provision responsiveness check

[speigg]

Summary

Responsiveness check often gets stuck in restart loops in local dev, because the fetch until timeout logic was incorrect. This fixes the problem.

This pull request refactors the instance server status fetching logic in instance-provision.class.ts to use a retry mechanism with await. This simplifies the code and reduces warnings.

• Add a retry variable to control the fetch loop of instance server status (link)
• Replace the fetch call with a while loop that uses await and checks the retry variable (link)
• Move the warning log message to the end of the instance-provision.class.ts file, where the unresponsive instance server is removed (link)

To fetch the server status with grace
We use a retry variable in place
With a while loop we wait
And avoid warnings we hate
Making the code more readable and clear in this case
