Add sleep between retires in bindings

In bindings.py the common retry() function uses a busy loop to retry, in
some cases the busy loop just increase the work loads of mapper and the
caller still get the ObjectPathInUse exception. It's better to sleep for
a while between retries.

A sleep interval is added as parameter default to 0, so the change does
not break existing functions. Then the caller has an option to pass a
sleep interval to indiciate it would sleep for an interval between
retries.
