Create Nuxeo Drive configuration validators

The goal is to create validators for configuration files:

• Local config uses INI data.
• Server config uses JSON data.

I do not yet know where to put this, but I would like to make validators available in the documentation:

• There would be a textarea.
• One could copy-paste configuration contents.
• Click on "Validate" and get details.
• Example: https://duckduckgo.com/?q=json+validator

Results:

• If there are errors: display them
• If there is no error:
  • If there are parameters that use default values, warn the user.
  • Return the configuration contents well-formatted (see below).

The validator will have to take care of parameter names: my-parameter, my_parameter or even MY-ParaMETER and they all are valid and referring to my-parameter.
So when a configuration is valid, the tool should return normalized parameter names, alphabetically sorted and remove ones using default values.

The validator will also ensure that the value entered is the same type of the one required. This is to prevent issues when one would use client_version = 4.4 (float) when client_version = "4.4.0" (string) is needed.

I can provide a list of parameters and their values.

Ideally, the server configuration validator would be located at https://doc.nuxeo.com/client-apps/how-to-configure-nuxeo-drive-globally/, and the local configuration validator at https://doc.nuxeo.com/client-apps/nuxeo-drive/#configuration-file.
