More consistently report errors launching outbound agents. (pull 8675)

Deprecate all configurable options in Launch agent by connecting it to the controller (inbound in JCasC), as these are only useful in conjunction with the deprecated jnlpUrl mode. (pull 8762)
The jnlpUrl ${JENKINS_URL}/computer/${AGENT_NAME}/jenkinsagent.jnlp argument to the agent JAR has been deprecated. Use url ${JENKINS_URL} and name ${AGENT_NAME} instead, potentially also passing in webSocket, tunnel, and/or work directory options as needed. (pull 8773)

Rework node monitor configuration. (issue 72371)
Allow configuration of disk thresholds globally and for each agent. Improve the warning when disk space is too low. Ensure agents are taken offline when disk space is low. (issue 72009)
Fail fast when attempting to load a broken plugin that contains the Jenkins test harness in production. (pull 8714)
Add packaging support for Unix domain sockets. (pull 442 (packaging))

The tunnel property on an inbound agent was inadvertently broken for JCasC usage in 2.437. It remains deprecated and usages should be deleted (regression in 2.437). (pull 8793)
Fix SimpleScheduledRetentionStrategy on inbound agents. Allow suspended inbound agents to again accept tasks when they are reconnected and the configured scheduling policy is enabled. (issue 72370)
