pipe subprocess logging to std out and std err

[touchaponk]

This pull request introduces logging for the subprocess's standard output (stdout) and standard error (stderr) streams`. The changes ensure that output from the subprocess is captured and displayed in the current process's logs for better debugging and monitoring.

Enhancements to subprocess logging:

• Added an asynchronous task _print_stdout to read and log lines from the subprocess's stdout stream, throttling the loop to prevent excessive CPU usage.
• Added an asynchronous task _print_stderr to read and log lines from the subprocess's stderr stream, similarly throttling the loop for efficiency.

@ehartford could you please see if we can merge the PR since right now longer mcp server response will hang up the client
