RFR: 8050: JMC Automated Analysis should improve the messages when ignoring to evaluate some rules. [v2]

[Suchita Chaturvedi]

> One of our customers requested to see a detailed _Ignore Reason_ whenever we ignore any rule in JMC. Rather than just saying Ignored. As part of this PR, we have added a new field Ignored Reason which will be displayed for all the Ignored Rules. It will give a clear idea about the missing event availability requirement.
