Please do not take the focus every time OmniSharp shows something in Output Tab

## Environment data
all the versions I have ever used

## Steps to reproduce
Open vscode with C# extension installed, do anything, if OmniSharp shows something on the Output Tab, that tab takes focus and interrupts user actions

## Expected behavior
The user actions aren't interrupted by OmniSharp outputs

## Actual behavior
The user actions are interrupted by OmniSharp outputs

This is very annoying and frustrating, please please do something about it, if someone needs it by default put it in some configuration I'll be pleased to do the clicks in order to prevent this from happening
