nice progress ;=)

I moved the default settings out from the code to a settings.json in the 
qt
resources.

This allows for easier manipulation of the defaults than coding the json
data in C++.

See

https://cgit.kde.org/kate.git/commit/?id=ac9dabc1f42af096309850b9a21254ff946664b6

I added an alternate "commandDebug" for the debug variant of the command
if the env var is set to LSPCLIENT_DEBUG.

I added some default setting for go LSP server, too, works nicely here 
;=)

Will try if I can add some more server configs.

Greetings
Christoph
