Harmonize the configuration properties for Undertow to match the changes
made for gh-2491.
Move `spring.undertow.accessLog*` to `spring.undertow.accesslog.*`
- Apply project’s code formatting and conventions
- Don’t use the IO and worker thread configuration when creating the
worker for the AccessLogReceiver. The IO and worker thread
configuration is for HTTP request processing and a worker in its
default configuration should be sufficient for the access log
receiver.
- Don’t use a temporary directory as the default for the access log
directory. A temporary directory makes (some) sense for Tomcat as it
requires a directory for its basedir. Undertow has no such
requirement and using a temporary directory makes it hard to locate
the logs. The default has been updated to a directory named logs,
created in the current working directory.
- Document the new properties in the application properties appendix
Closes gh-3014
