This don't remove jQuery completly, but it allow us to clean up the remaing part

   It is a useless block

   Replace tv4 by cfworker-jsonschema in order to support more recent schemas.
   Use ref-parser rather them custom expandSchema to build a expanded json schema.

    cfworker json schema was built from https://github.com/cfworker/cfworker/tree/main/packages/json-schema source code.

   Allow the default sample use Additional Properties for now, a more restricted version of it can be included on another file.

  This trigger validator to display error messages.

  This change isn't ideal, but this is minimal before a major refactoring

   Click only works when you click on buttons, while change quite often calls getContent/checkValidity, causing the this test to be more stable.

  Add samples for required on editor parameter (for tests)

   The errors should be properly displayed.

   This may contains extremely simple with 1 field of each type for make test parameter easier to be written.

   This makes tests much easier to be written, for while asserting the result as a simple hashed string.

   Also include header link to return

Fixup of 89863d6c

For links like this:

$ ls -l /dev/disk/by-path/pci-0000:42:00.0-nvme-1
lrwxrwxrwx 1 root root 13 Oct 25 15:19 /dev/disk/by-path/pci-0000:42:00.0-nvme-1 -> ../../nvme7n1

os.readlink() returns "../../nvme7n1" while we want "/dev/nvme7n1".

because json output is different on python2 and python3 and cli is only
used on python2, we don't test the exact output in python2.

This is particularly needed for old OS with python2: very old versions of
pip are trying to install latest version of eggs no matter their python2
compatibility whereas pip 20 is making sure to install only python2
compatible eggs.

   Not required to do doActionFor here.

   Update tests only.

   Regularisation Requests can be auto cancelled even if they are Operator assigned. This prevents extra unnecessary extra mensagens.
