Description: Support 0.9-pre release of Prometheus client
 The latest release of Prometheus client does not allow one to set a value on a
 Counter. Setting values on Counters was already deprecated on version 0.8.
 .
 This patch basically convert to Gauges all the Counters whose values are set
 by the no longer existing method.
