Support dynamic client_id ?

[ptgamr]

Currently, we mount our app is mounted to a dynamic segment of the URL, what we would need to do is to use different client_id depending on the URL.

http://localhost:4200/namespace1 - use client_id = namespace1
http://localhost:4200/namespace2 - use client_id = namespace2
http://localhost:4200/namespace3 - use client_id = namespace3
...

It is not possible at the moment because the client_id is defined fixed inside environment.js file, and we only build 1 app. Would you have any suggestion how to achieve this? Can we somehow modify a config at runtime? or perhaps provide a function to get out values like: client_id, host, tokenEndpoint etc....

I might need some input here, happy to submit a PR once I know more about how the API should look like.

Thanks,
