* cli: Allow setting the current node region with flag or env variable
Also add region to "starting LiveKit server" log.
* routing: Add region to node registration
Register the node's region on the selected router so it can be used for
region aware node selection.
Also add the region to the list-nodes output.
* regionaware: Set minDist to zero for the current node
If you don't set the minDist when leaving the loop early for a node that
matches the current region, the minDist value with still be at max. This
causes the the wrong node to be selected if the current node is the
first one the loop passes through.
Add a test that validates this change. The new test fails if this new
change is not in place.
