* Add fixes for failure in specialization * reduce specialization in progress and remove expired requests from queue when specialization is timed out * rename markSpecializationFailure and remove logger from the queue * refactor clean up code in api.go and add test case for queue Details: - Cleanup svc waiting for the counter in the pool manager if specialization fails - Cleanup active requests counter in pool manager if client exists the demand for function service while we have allocated function service - Consider specialization timeout if pod ready timeout > specialization timeout in waiting for ready pod. We also consider if the request to choosePod is cancelled. - We ensure if we have requests waiting for service requests but if there is no pod in the specialization we clean up those. --------- Signed-off-by: Sanket Sudake <sanketsudake@gmail.com> Co-authored-by: Pranoy Kundu <pranoy1998k@gmail.com>
