show-caches: Improve memory reporting
The way memory was reported was almost useless. Change it to show
the actual values, and the equation that determines how these are
put together to form the current usage.
Include some additional data including server version, current time,
process uptime, active SSH connections, and tasks in the task queue.
The --show-jvm option will report additional data about the JVM,
and tell the caller where it is running.
