Support Double Wildcard Custom Domains

For multi-tenant applications, we require the ability for Azure to support double wildcard custom domains.

Single wildcard custom domains are currently well supported, i.e.

*.mydomain.com

catches all unmapped, single subdomain urls e.g. level1ex.mydomain.com, level2ex.mydomain.com etc

The issue (which isn't documented: see forum post below) is that secondary level wildcards are not supported at all by Azure:

e.g. www.level2.mydomain.com will result in a 404 error.

Why is this important? in a multi tenant environment, with lots of customers on different subdomains, it is best from an end-user perspective to support a www. subdomain prefix, as that's what 99% of non-technerati do when navigating to a website!

i.e. typing in www.level2.mydomain.com should be resolvable by Azure, just as single-level domains are, and not result in a 404
