We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Filename collision due to case-sensitivity in Keysight folder
When pulling the qcodes repository on Windows, there is a filename collision between the uppercase and lowercase Keysight folders.

The error message is as follows:
```bash
$ git clone https://github.com/QCoDeS/Qcodes.git
Cloning into 'Qcodes'...

warning: the following paths have collided (e.g. case-sensitive paths
on a case-insensitive filesystem) and only one from the same
colliding group is in the working tree:

  'qcodes/instrument_drivers/Keysight/__init__.py'
  'qcodes/instrument_drivers/keysight/__init__.py'
```

I propose we remove the lowercase keysight folder as it has now been deprecated for over 2 years.

### System
Windows/OSX and other OS's with case insensitive file systems.
