[#2429] Add completeness property for software modules (#2765)

* add `min artifacts` requirement on the Software Module Type level for Software Module completeness
* removed `complete` Distribution Set property from DB - calculated runtime
* Distribution Set and Software Module completeness is calcualted on demand in memory (TODO: implement cache)
* locking of Software Module now requires the software module to be `completed`
* removed 'complete' search field for DistributionSet type. Still keep (DEPRECATED) limited support for search with 'complete' -
  only on the first level of expression and with AND. I.e. complete==true, complete==false and id=in=(1, 3) is suppoted,
  while complete==false or id=in=(1, 3) and id=in(1, 3) and (type==os and complete==true) are not
