Currently Graph api does not support custom Graph Url

[raghucha]

Describe the bug

Currently in BaseGraphRequestAdapter we have support for the below list of cloud URL

cloudList.put( Clouds.GLOBAL_CLOUD, "https://graph.microsoft.com" );
   cloudList.put( Clouds.USGOV_CLOUD, "https://graph.microsoft.us");
   cloudList.put( Clouds.CHINA_CLOUD, "https://microsoftgraph.chinacloudapi.cn");
   cloudList.put( Clouds.GERMANY_CLOUD, "https://graph.microsoft.de");
   cloudList.put( Clouds.USGOV_DOD_CLOUD, "https://dod-graph.microsoft.us");

However in the GraphServiceClient there is no option to configure the URL

here is sample code

 AzureIdentityAuthenticationProvider authenticationProvider = new AzureIdentityAuthenticationProvider(
            tokenCredential, new String[0], scopes);

        GraphServiceClient graphClient = new GraphServiceClient(authenticationProvider, httpClient);

Expected behavior

I feel that GraphServiceClient should have an option available to configure the base URL from the cloudList

GraphServiceClient graphClient = new GraphServiceClient(authenticationProvider, httpClient);

How to reproduce

Try creating GraphServiceClient with custom baseURL
