Increase listener limit for Application Gateway

Application gateway has a very low listener limit (20 listeners / certificates). This severely limits it's usefulness for multi-tenant/domain applications where a web farm / service hosts many endpoints. IIS itself has no such small limit, but due to constraints on certificate deployment in cloud services, Application Gateway is the only clear path to wide scale SNI based SSL hosting. With it's low limit, it does not come close to meeting our use case. I would suggest the limit be removed or set to a very high limit like 10k+ so many certificates could be bound to host many different domains.

We have raised the limit to 100 recently. We are regularly reviewing the limits and will continue to look for opportunities to raise the limits even further. Stay tuned :)
