GotSomeSpaces Counters Group (GotSomeSpaces_group)

- GSS1: Number of times we tried to reclaim callback space and failed to find a suitable host for which to clear callbacks.

- GSS2: Number of times we repeatedly tried to reclaim callback space and never found any host for which to clear callbacks, and cleared callbacks on the host for which we were adding a callback.

- GSS3: Number of times we tried to reclaim callback space and we reclaimed space by clearing timed-out callbacks.

- GSS4: Number of times we tried to reclaim callback space and we found a suitable host to try to clear callbacks on.

- GSS5: Number of times we tried to reclaim callback space and we cleared callbacks on a host that was waiting to have a callback added to it.
