Design: Form Integrations

[JakeUrban]

What problem does your feature solve?

Anchors need to be able to adjust the information collected for KYC, but currently have no way of doing that without forking the codebase.

What would you like to see?

A design for form integrations that allows for the anchor to define and validate forms registered with polaris. It should the same pattern as #10 for consistency.

What should this feature provide?

It should provide an API for defining forms.

• This includes the field list and associated validation functions. This can be done with Django Forms.
  It should provide a function for processing the information post-validation
• The anchors could use this to persist some of the information collected.

Once the form is validated and processed, the polaris endpoint using the custom form would resume control to continue the withdraw or deposit flow.
