Duplicate created Entity

## What?

If something can be created (Eg, Events, Grok Patterns, Pipeline Rules, etc) it would be nice to be able to Duplicate it.
Perhaps even default it to a `disabled` state until it is modified, or push the User directly into the Edit workflow to update the Title and contents.

## Why?

Some Users will need similar options in multiple entities.
Currently, this requires building out a CURL command to run against the API multiple times, or going through the entire UI process repeatedly.
If we offered a 'Duplicate' function, this would minimize the amount of effort required by the User to have multiple similar entities and they can modify the contents as needed.

This can come with the drawback of duplicated processing if the User perhaps forgets to modify the Duplicated artifact. We should consider showing a persistent UI notification that would inform the User of this and then provide a link to Fix or Ignore.
Then in the List/Index page of any Entity with duplicated data would show a UI notification inline with the affected item(s).
