connect to #2036
This is a follow-up story of PR #3667.
As a quick fix, that PR fixes the controller generator by adding a new prompt isIdOmitted, and creating the corresponding controller class differently.
There are two more improvements which need more time to address, so I open a new issue here.
Suggestion
Update the controller class in @loopback/rest-crud to reflect the id property's configuration.
