EI_INTERNAL_HTTP_INBOUND_ENDPOINT Listener shutdown abnormally when we invoke the HTTP health check endpoint before server startup

[niranRameshPeiris]

Description

After updating the docker image of the MI-1.2.0 from update level 53 to 94, the HTTP health check is not working fine. We were able to identify port 9201 is not up and running even after the server started. And we have seen the below exception in the wso2carbon.log file as well.
