* Prom exporter structure * update prometheus exporter with master and add example. * remove distributedcontext from prometheus example * docs and interface checker * make precommit * make precommit & remove "OnRegisterError" * coerce values to float * return register errors and maybe fix precommit? * add option to specify a prometheus.Registry * make exporter implement http.Handler interface * fix map keys bugs * remove unused const * fix modules dependencies. * add support for histogram * get metrics with labels values only instead of a labels map * make exporter implements label encoder interface * encode labels if the encoder is different. * split metrics on several files and encapsulate them in structs * make pre commit * unexport 'sanitize' * remove 'AllValues' in favor of 'Points' and change to 'NewDefaultLabelEncoder' * add prometheus tests * remove newlines on struct declaration * formatting * rewording * imports * add todo on labelValues * blame myself for todo (: * add todos on sanitize * add support for summaries. custom remove label encoder. * imports * imports * update with upstream
