Several dreivers don't support changing driver_handles_share_servers
but only support True or False. For such drivers, it's not really
helpful to expose an interface to set the parameter. Futhermore, it's
just redundant to require the parmaeters is set with the proper value.
This change deprecate the driver_handles_share_servers parameter about
share drivers which support only one of True or False.
