  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'...
  remote: Enumerating objects: 1522, done.

  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.
