Deletes a Subnetwork Connection. If the SNC has more alternative routes, then the operation deletes the SNC, its intended and all bkp route(s).
This operation also applies to bundled SNCs. In the case that the mustRemoveGTPs attribute is set to "TRUE" and the EMS cannot remove all the interior GTPs,  the EMS should return a list of the GTPs that could not be removed in the errorReason output parameter. The errorReason will be "not all interior GTPs could be deleted" - this will be followed by the names of the GTPs that could not be deleted.

Operation Exceptions:
1. NOT_IMPLEMENTED - Raised when the EMS does not provide this operation.
2. INTERNAL_ERROR - Raised in case of non-specific EMS internal failure.
3. INVALID_INPUT - Raised when any input parameter is syntactically incorrect (e.g. sncName does not refer to a SNC
    object).
4. ENTITY_NOT_FOUND - Raised when sncName references an object that does not exist.
5. NOT_IN_VALID_STATE - Raised when the SNC is in the partial or active state.
