Component: Date input form

[SaptakS]

As discussed in #51 (comment), in our next iteration we will want a date input with a better UX. The idea would be some for of a date picker that opens as a dropdown. For this issue, we have 2 requirements:

• Design for the dropdown
• Implementation of the design using QML

Some of the other questions that came up from a user testing while using our current date input field is:

• can there be a date picker?
• Or a prefilled date?
• Or a quick picklist for dates? 3 years from now, 4 years from now
• What's stopping me from using a date like 3045/01/01?
• What should I use? Is there a best practice?

I think some of the things that I see from this is:

• Adding expiry date format validations
• Come up with validation rules (i.e. do we want to have an upper limit like not more than 10 years unless it never expires or something?)
• Better documentation about best practices
