webui: field and widget binding refactoring

This is a Web UI wide change. Fields and Widgets binding was refactored
to enable proper two-way binding between them. This should allow to have
one source of truth (field) for multiple consumers - widgets or something
else. One of the goal is to have fields and widget implementations
independent on each other. So that one could use a widget without field
or use one field for multiple widgets, etc..

Basically a fields logic was split into separate components:
- adapters
- parsers & formatters
- binder

Adapters
- extract data from data source (FreeIPA RPC command result)
- prepares them for commands.

Parsers
- parse extracted data to format expected by field
- parse widget value to format expected by field

Formatters
- format field value to format suitable for widgets
- format field value to format suitable for adapter

Binder
- is a communication bridge between field and widget
- listens to field's and widget's events and call appropriate methods

Some side benefits:
- better validation reporting in multivalued widget
