Add ErrorCode to ChainName histogram in HltEventLoopMgr
Add histogram to monitor names of chains that were executed when an error occurred. To test the mechanism RandomError hypo algorithm was added - it returns StatusCode::FAILURE with a given probability (configurable via ErrorProbability).
The algorithm is not included in any chain now but was tested locally. An example of a histogram will be available on JIRA.
