Enable full search of Logstash config

[FreerideTheWorld]

Describe the feature:
Enable the ability to search the entire Logstash config in the Stack Management --> Logstash Pipelines --> page.
Describe a specific use case for the feature:
I used to be able to hit Ctrl +f when editing the Logstash config file in the Kibana UI. At this time when I do that all it will search is whats visible within the config window. In our use case we have a long list of IP's we check, tag and then ship to the appropriate index. When tickets come in for the update or removal of IP's I used to be able to run a quick check to see if the IP has already been added. Now I can't check the whole config so I need to copy and paste it into Notepad++, run the check, and if there are duplicates scroll to the location of the IP.

A similar issue is that the ability to copy information out can be done with Ctrl +v but can't be done with the mouse. I'm not sure if these are related issues but I figured I'd add it here.
