[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This adds bt_gatt_server_set_permissions which can be used to
enabled/disable permission checking before operations which can be
useful on testing only environment where encryption/pairing is not
desirable/needed.
