bt: Add option to ena/dis BLE service change registration

Browse source 
Add option to enable/disable automatic registration of BLE Gattc
service change notify. Which sends in parralel
(with user message flow) commands to BLE server which
sometime leads to GATT_BUSY.
(BLE server is able to handle only one command at time)

Closes https://github.com/espressif/esp-idf/issues/1575
