Customizable Validation Messages

[sdirix]

• Within the array control there is a summary of validation errors. However since the messages are local to each control the summary does not make much sense. See screenshot below from array control example of jsonforms.io:
  
• Enum values are rendered as drop boxes. Therefore the validation message should be equal to one of the allowed values seems strange. See screenshot below from Rule example of jsonforms.io:

ajv seems to supports customizable error message via ajv-errors, although it seems a bit strange that the error message is placed within the schema itself. For our uses case, I'd rather place it in UI schema and then do some kind of pre-processing/transformation of the schema for ajv. We need to pay attentation how this will integrate with i18n (which perhaps also needs to re-work) and #923.

Error messages can now be customized via the new i18n support in JSON Forms 3.0.
