Dear maintainers

This pull request is a proposed implementation for the graceful termination of the init process through two modifications

a timeout named a graceful termination that corresponds to the time, starting when the SIGTERM is received, after which the init process is over
a new HTTP endpoint (/runtime/stop) for shutting down properly the init process

Thank you

Have a use case for this as well since I need to test proper handling of sigterm traps for my runtime. Thanks for putting the work in for this.
