> The wildfly server currently -terminates immediately- performs a standard (non-graceful) shutdown in response to a TERM signal.  To achieve a -clean- graceful shutdown requires invoking the CLI tooling.  This is particularly problematic in container environments like kubernetes where the container process (wildfly in this case) is going to get a TERM signal when the container needs to be moved. 
> While it's possible to wrapper the process and handle the TERM and then invoke the CLI, it would be preferable for the server process itself to cleanly handle a TERM signal by waiting for in-flight requests to complete (w/ some grace period of course).
> Having this as configurable behavior would be good if there are backwards compatibility concerns about introducing this behavior change.
