Parameters of all commands under "az ml service" should have long forms in addition to short forms

**Is your feature request related to a problem? Please describe.**
Some commands under "az ml service" have parameters which only have short (one letter) forms. This makes scripts using these commands less readable and breaks user expectations, because the same parameters in other commands do accept long forms.

command|parameter|short form|long form in other command(s)
-----------|-----------|------------|----------------------------------
az ml service create aci|execution_script|-s|--execution-script (ml image create container)
az ml service create aci|runtime|-r|--runtime (ml image create container)
az ml service create aks|service_name|-n|--name (ml service create aci)
az ml service create aks|num_replicas|-z|no existing long form, suggestion: --num-replicas
az ml service create aks|execution_script|-s|--execution-script (ml image create container)
az ml service create aks|runtime|-r|--runtime (ml image create container)
az ml service update aks|service_name|-n|--name (ml service create aci)
az ml service update aks|num_replicas|-z|no existing long form, suggestion: --num-replicas
az ml service run|input_data|-d|--input-data (ml image run)

**Describe the solution you'd like**
Please add long forms to these parameters.
