Francois Tur 05204ef142 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
