Kit::Errors - Add errors taxology

[nathan-appere]

Context

We need a unified way to handle, categorize & display errors.

We need to figure out:

Wrappers

• ActiveRecord errors
• DB errors
• Contracts

Connectors

• JsonAPI
• Forms
• Error reporting (through events?)

Taxonomy

• Internal vs External ? (clearance for user display?)
• Hiearchy / grouping? (Ex: alfo error wrapper + when we want to continue processing and aggregate)
• Payload format
• Transforming attributes / params name by layer (contextualisation)
• I18n
