🔍 Description

Issue References 🔗

This pull request aims to make the Jetty server stop timeout configurable.

The RESTful frontend protocol has been enabled by default since 1.8.0, while a side-effect is observed, the process shutdown is always blocked by the Jetty server until reaches the default 30s timeout.

Describe Your Solution 🔧

Two configurations are introduced in this PR

kyuubi.frontend.trino.jetty.stopTimeout=5s
kyuubi.frontend.rest.jetty.stopTimeout=5s

while the 5s is chosen as the default value according to https://git.eclipse.org/c/jetty/org.eclipse.jetty.project.git/tree/jetty-server/src/main/config/etc/jetty.xml?h=jetty-9.3.x#n124
