L3_Templates: add ts_ML3_MO_CC_DISC

To simulate an MS initiated call release at the MSC, a MO CC DISCONNECT
is required. So far msc's f_call_hangup() has some really weird
sequences of MNCC events. This is one preparation to fix that.

Will be used by MSC_Tests.TC_call_re_establishment in
Ifdff5573eeb3b3d41e8599b9b0228411d2576864
