Rudy/golang expvars

Agent check to report values exposed in go app by expvars.

Expvar will by default expose information about the go runtime and also allow to add custom variables.


@remh Do you have an opinion on the way used to specify what metrics to report?
It's not possible. I can add it if you think its necessary but I was afraid of users reporting too much metrics they don't care about + losing the possibility to define what is a rate vs what is a gauge.
