Allow setting example paths and queries for DocService (line#2546)
Browse files Browse the repository at this point in the history 
Motivation:

Currently, a user cannot set example paths and queries. line#2195
The endpoint path or queries are only set automatically when
opening a URL that contains `endpoint_path` or `queries` as params.

Modifications:

- Add `examplePaths` to `DocService` and `DocServiceBuilder`
- Add `exampleQueries` to `DocService` and `DocServiceBuilder`
- Show `examplePath` if the `endpoint_path` is null and the `examplePath` is not null
- Show `exampleQuery` if the `queries` is null and the `exampleQuery` is not null
- Make `ENDPOINT PATH` input visible with read-only if a path is exact type 

Result:
You can now set an example path and queries for `DocService`
Fixes line#2195
