When glider updates status of a proxy (...status from ENABLED to DISABLED), it would be helpful to suffix those log lines with information about currently ENABLED proxies.

For example, instead of:

group.go:162: [group] localhost:9001(0) changed status from DISABLED to ENABLED

write something like:

group.go:162: [group] localhost:9001(0) changed status from DISABLED to ENABLED (25 of 30 currently enabled)
