Rethink architecture concepts

[ivan-kleshnin]

Current concepts

type

Independent.

JS types

validator

Depends on type.

1. Converts input types
2. Provides validation errors

   model

Depends on validator.

1. Converts input types (with validator)
2. Raises an error for invalid input
3. Generate defaults for some optional input

This violates the Single Responsibility principle.

maker

Depends on model.

1. Generates values for required model input

   Proposed concepts

   type

Independent.

JS types (Tcomb types) + Custom types

1. Raises an error for invalid input

   parser

Independent.

1. Converts input types (with Globalize)

   maker

Depends on model.

1. Generates values for all inputs

[ivan-kleshnin]

Consequences:

1. Remove JOI dependency.
2. Add TComb and Globalize dependency.
3. Remove model concept. Roughly replaced with types. E.g. User will be a Tcomb type.
4. Remove generate value for optional input behavior.
5. Add parse & format concept independent of validation.
