[IMP] sale_crm : create partner on new quotation if no customer set on opportunity

When creating a quotation from a opportunity that does not have any
customer set, we ended up on a quotation without any customer or any of
the contact information entered on the crm.lead.

If no customer is set on the opportunity, when hitting New Quotation button,
a modal is displayed to ask the user what to do to fill in the customer field.

- Create a new customer : Use the information from the opportunity to create
automatically a res.partner. Set the res.partner on the quotation
and on the opportunity.
- Use an existing customer : Set this customer on the quotation
and on the opportunity.
