[FEA] Web-hosted cuopt client interface

[atomic]

Is your feature request related to a problem? Please describe.
The python client's current implementation CuOptServiceSelfHostClient assumed that the model can only be interacted through local hosting or exposed IP and port endpoint. However, extending the current functionality to support web-hosted cuopt model is very trivial as the current interaction is done through request library

Describe the solution you'd like
Additional class CuOptServiceWebHostedClient which extends the base CuOptServiceSelfHostClient and re-use most functionalities

Describe alternatives you've considered
Alternative considered is to remove the authentication layer from the web hosted endpoint, and re-use the existing CuOptServiceSelfHostClient client which is not secure
