Add <CheckoutButton />

[roygrv21]

Let's create a button that would redirect the user to the payment page. Let's not put too much effort in styling as it has to be changed in the later stage once we are given the specific designs.

The payment link would be provided by upay members, let's have a dummy button for now?

I will create it, you can assign the issue.

@MadhavBahlMD yes this is only for UI, the functionality will be probably introduced using container pattern or redux like actions.
