Domains: Adapt domain registrant verification page to be used with DSAPI reseller domains

[leonardost]

Proposed Changes

This PR updates the domain registrant verification landing page (/domain-services/registrant-verification/) to be used with DSAPI reseller domains.

A new reseller=reseller-name query parameter can be added to the URL. When that's added, references to WPCOM links and support pages are removed. If the reseller is tumblr, the Tumblr logo is shown in place of the WordPress logo.

Screenshots

• Success

• Email already verified

• Expired email

• Mismatched email address

• Error message

Testing Instructions

• Open the live Calypso link or build this branch locally
• Hack your backend's /domains/{domain}/verify-email endpoint to return different success and error responses
• Access the registrant verification landing page with some example query parameters, e.g. /domain-services/registrant-verification?domain=example.com&email=example@example.com&token=1234&reseller=tumblr_ote
• Ensure the different backend responses' show pages as shown in the screenshots above

Here is how your PR affects size of JS and CSS bundles shipped to the user's browser:

App Entrypoints (~294 bytes added 📈 [gzipped])

name                   parsed_size           gzip_size
entry-domains-landing       +617 B  (+0.1%)     +294 B  (+0.2%)

Common code that is always downloaded and parsed every time the app is loaded, no matter which route is used.

Legend

What is parsed and gzip size?

Parsed Size: Uncompressed size of the JS and CSS files. This much code needs to be parsed and stored in memory.
Gzip Size: Compressed size of the JS and CSS files. This much data needs to be downloaded over network.

Nice! I think we should also hide the button in getExpiredState as I'm pretty sure we won't be able to resend the verification email. But other than that I think it's working great!

Thanks for the review @hambai, and that's a good point! I've updated that page to hide the button and changed the message accordingly.
