How do we style the forms consistently?

[matheo]

The library have no styles on its dyn-form, dyn-group and dyn-factory components.
Initially, we've made some "global" style customizations from the root component using dyn-form.
Right now we are able to set some CSS classes via DynConfig.factory.cssClass and they are placed by the DynControls in the appropiated place. Most of the styling will depend on the provided DynControls anyways, but we should be able to have consistency between the controls we use.

It's the prime time for ViewEncapsulation.None?
A shared stylesheet with adjustments will be required when we consume third-party controls?
What do you suggest on this regard?
