plugin/pkg/uniq: add (#1733) Spin this out the metrics package so we can use it in the health one of well to fix some reload bugs. 2018-04-25 11:45:09 +01:00			`package uniq`

Metrics registered on wrong prometheus registry (#2246) * - UT on metrics verifying that all plugins of all blocs have their metrics collectors declared * - fix error msg * - redirect Registry of metric to the one that handle the listener - allow duplicate of metrics collector on the same Registry (case of same plugin in 2 blocs listening metrics on the same address) * - fix change of signature * - ensure cleaning metrics before starting the test (metrics collectors are global vars .. and re-used by several tests) * - I think I fixed this test. Ensure correct mn of hits and clean metrics before test. * - fix typo in error msg - proposed at review * - fix typo in comment * - remove ResetMetrics functions - change a way to test the numeric metrics : get the diff between begin and end of test * - oops. removing debug logs 2018-11-01 15:56:00 -04:00			`u.Set("test", func() error { i++; return nil }, nil)`
