wireproto: move clonebundles command from extension (issue4931)...

wireproto: move clonebundles command from extension (issue4931) The SSH peer class accesses wireproto.commands[cmd] as part of encoding command arguments. Previously, the wire protocol command was defined in the clonebundles extension. If the client didn't have this extension enabled (which it likely doesn't since it is meant as a server-side extension), then clients attempting to clone via ssh:// would get a crash due to a KeyError accessing wireproto.commands['clonebundles'] when cloning from a server that is advertising clone bundles. Moving the definition of the wire protocol command to wireproto.py makes this problem go away. A side effect of this code move is servers will always respond to "clonebundles" wire protocol command requests. This should be fine: the server will return an empty response unless a clone bundles manifest file is present and clients shouldn't call the command unless the server is advertising the capability, which only happens if the clonebundles extension is enabled and the manifest file exists.
