Describe the feature

In ElvUI, there is an option to show a cast that is interrupted, with a configurable amount of 'time to hold'. indicating how long the 'interrupted' bar should stay on screen before disappearing. I would like to see this in Cell_UnitFrame's cast bars, along with some extra features (listed beneath) that ElvUI does not support.

Below is an example as it appears in ElvUI:

Describe the implementation

I would like to be able to:

• Choose the text label, with it defaulting to the word Interrupted
• Optionally tell you the spell name of the cast that was interrupted
• Optionally tell you the name of the unit that interrupted the cast, colored by the unit's class name, e.g. "Interrupted (Playername)" where playername is pink if the player is a paladin
• Choose the duration for how long the bar stays on screen after changing to the 'Interrupted' state, defaulting to 0.7s (the default in ElvUI)
