Draft: Feat/add error handling middleware

[Lutherwaves]

This is still a draft

This PR will implement the following changes (but hasn't already done it)

• Create error handler middleware
• Define base errors and handle Internal Server Error ; Error Not Found ; Bad Request ; Storage Adapter Error
• All routes/services/adapters can return errors, which will be handled by the middleware
• Formatter (currently used in the routes) is moved to ApplicationErrorHandler

Stretch:

• Error chaining in the cause

Closes #5
