clonebundles: adds a auto-generate.serve-inline option
This new option disable the "external" serving of auto generated bundle in favor
of using the new "inline bundle" feature that allow serving such bundle through
the mercurial protocol.
This is a less efficient, but very easy to setup way to start using clone bundle.
