Allow to close tabs by hovering over a tab and clicking the middle mouse button.
Just like in web browsers. :)

AnnotatedServiceBindingBuilder and VirtualHostAnnotatedServiceBindingBuilder currently don't share a common interface for its methods, such as pathPrefix() and exceptionHandlers(). This means, a contributor can add a builder method to one builder but not to the other by mistake. By making both builder extend a new interface AnnotatedServiceConfigSetters, we could prevent such a mistake.

Is your feature request related to a problem? Please describe.
I want to use ETCD's ttl, and I noticed that there are some lease methods (LeaseGrant and so on) exposed from client, but I can't figure out how to use them.

Describe the solution you'd like
Add some usage examples in README.md.

Thank you for your creating the great client again.

During tab completion currently documentation is shown as additional information.

However when displaying the reply messages no documentation is shown in those messages.

It would be nice to also show documentation there.

maybe make it possible to disable via config or cli arg
