Implements blueprint multi-process-api-service This is based on Huang Zhiteng's patch. This patch adds support for running services as multiple processes. This is primarily intended to be used with the API service as a way to provide more concurrency than eventlet can sometimes provide. A SIGTERM or SIGINT signal will cause the parent process to gracefully terminate the child processes, allowing them to finish processing the requests currently being processed. The parent will wait for the children to finish before exiting. Change-Id: Ie6d6802626eb42d5e64c4167be363fbf6cea2a1b
