Suggest a fix/enhancement

Handle the Constant QueryParameter Value in the generate ts library. The only value that can be set to this parameter is the one defined in the enum

Since, there are no updates on this Issue.
I have made a fix by modifying

1. CodegenParameter.java and
2. api.service.mustache

Thanks

Hey again @kunal-pmj, this LGTM, i would just recommend to edit the petstore sample adding this case, only if it's not present. and based on this, update the typescript-angular samples. wdyt?

i could give you a hand if you need help.

[kunal-pmj]

Let me add the tests. I will contact you if I need any help.

thanks
