Wez Furlong 28f7b4a0b0 eden: show desktop notification for blob/tree fetch errors
Summary:
This commit causes a desktop notification to be shown if we generate
EIO or ETIMEDOUT responses via fuse; the prompt is intended to make it obvious
to the user that they need to connect to the VPN.

The commit by itself doesn't show a notification, it allows configuring a
command that can be run to do something to show a notification.

The test plan includes one such configuration for our corp environment.

* It doesn't trigger for thrift-originated downloads (eg: prefetch), only for
  VFS operations through FUSE.
* Ideally we'd know exactly when we have a network related error in the store
  code and use that to trigger the notification.  However, we have a rather
  convoluted set of importers and fallbacks today, one of which is interpreting
  a generic response returned from a pipe, so it is not especially clear
  exactly where we should locate the logic
