Create delete_parameter endpoint (#691)

Create delete_parameter endpoint







TSIA

## Test Plan
Follow dev README to setup the local editor:
https://github.com/lastmile-ai/aiconfig/tree/main/python/src/aiconfig/editor#dev,
then run this command
```
curl http://localhost:8080/api/delete_parameter -d '{"prompt_name":"get_activities", "parameter_name": "city"}' -X POST -H 'Content-Type: application/json'
```
Notice that the parameters are now deleted
