[ResponseOps][MW] Show active MWs in the rule details page

[cnasikas]

The rule details page does not show any information about active MW that affect the current rule. We should show the active MWs that affect the current rule.

• As a user, when reviewing a rule page, I'd like to see if there are active MW that detect alerts associated with this Rule. e.g: when reviewing rule X when 10 alerts are matched to the MW, so I want to navigate to this MW directly from the Rule view so I'll be able to exclude the rule id using the filter.
