Description of problem:
  After the Satellite upgrade (from 6.2.14) to 6.3.2 the '--owner' key/value is not recognized anymore with 'hammer host create'.

Version-Release number of selected component (if applicable):
  Satellite 6.3.2

How reproducible:
  # hammer host create --name rhel7-test --hostgroup-id 2 --organization org01 --location loc-int1 --build true --owner rainer --domain rr-int1.net --model-id 1 --interface ip=192.168.40.17,mac=52:54:00:fb:4e:16,subnet_id=1,primary=true,managed=true,provision=true
  
  # hammer host info --id 11 | grep -i owner
  Owner Id:   3
  Owner Type: User

  Satellite User: admin (3), rainer(4)
  Same issue with specifying '--owner-id' instead of '--owner':

Actual results:
  Host owner is the user who executed the 'hammer host create ...' command

Expected results:
  Host owner is the specified user ('--owner ...'). 
  This worked as expected with Satellite 6.2

Additional info:
  A workaround is to change the host owner after the creation, with:

  # hammer host update --id 11 --owner rainer
  Host updated

  # hammer host info --id 11 | grep -i owner
  Owner Id:   4
  Owner Type: User
