chg: make connect debug message less repetitive

chg: make connect debug message less repetitive

Before this patch, "connect to" debug message is printed repeatedly because
a previous patch changed how the chg client decides the server is ready to be
connected.

This patch revises the places we print connect debug messages so they are less
repetitive without losing useful information.
