This patch makes chasquid's monitoring server expose an OpenMetrics metrics endpoint. It adds a new package "expvarom" which implements an HTTP handler that exports expvar variables in the OpenMetrics text format. Then, the handler is registered by the monitoring server at /metrics (where most things expect it to be). The existing exported variables are also extended with descriptions, which is optional, but improves the readability of the metrics.
