clonebundles: remove advertisement of feature

I screwed up.

When clone bundles is enabled on the server and a compatible client
without the feature enabled clones, the server sends down an
advertisement saying to enable the feature. The server creates the
message which is printed verbatim on the client as an "output" part.
There are 2 problems:

1) The message doesn't respect the client's localization
2) The message contains a reference to the "experimental.clonebundles"
   option.

Since clone bundles is about to be marked as non-experimental and the
goal of the advertisement was to encourage clients to test the
experimental feature, let's just remove the broken advertisement since
it no longer serves a purpose.

Mercurial server when the bundle hosting service fails.

The following config options influence the behavior of the clone bundles
feature:

ui.clonebundleadvertise
   Whether the server advertises the existence of the clone bundles feature
   to compatible clients that aren't using it.

   When this is enabled (the default), a server will send a message to
   compatible clients performing a traditional clone informing them of the
   available clone bundles feature. Compatible clients are those that support
   bundle2 and are advertising support for the clone bundles feature.

ui.clonebundlefallback
   Whether to automatically fall back to a traditional clone in case of
   clone bundles failure. Defaults to false for reasons described above.

experimental.clonebundles

   If not defined, the order in the manifest will be used and the first
   available bundle will be downloaded.
