Error with ClusterHelper - Only 'http' and 'https' schemes are allowed

Summary: I'm using "couchbase://localhost" as a connection string and getting an error that only "http" and "https" schemes are allowed.

Repro:

1. New ASP.NET Core app
2. In Startup.cs, in ConfigureServices, do a ClusterHelper.Initialize
3. In the ClientConfiguration::Servers, I create a List<Uri> with one Uri = new("couchbase://localhost")
4. In a Controller constructor, I do ClusterHelper.GetBucket("default")

Actual:

Exception -->

{System.ArgumentException: Only 'http' and 'https' schemes are allowed.Parameter name: requestUri   at System.Net.Http.HttpRequestMessage.InitializeValues(HttpMethod method, Uri requestUri)   at System.Net.Http.HttpRequestMessage..ctor(HttpMethod method, Uri requestUri)   at System.Net.Http.HttpClient.GetAsync(Uri requestUri, HttpCompletionOption completionOption, CancellationToken cancellationToken)   at Couchbase.Configuration.Server.Providers.Streaming.HttpServerConfig.DownloadString(Uri uri)   at Couchbase.Configuration.Server.Providers.Streaming.HttpServerConfig.DownLoadConfig[T](Uri uri)   at Couchbase.Configuration.Server.Providers.Streaming.HttpServerConfig.DownloadConfigs(Uri server)   at System.Linq.Enumerable.Any[TSource](IEnumerable`1 source, Func`2 predicate)   at Couchbase.Configuration.Server.Providers.Streaming.HttpServerConfig.Initialize()   at Couchbase.Configuration.Server.Providers.Streaming.HttpStreamingProvider.StartProvider(String username, String password)   at Couchbase.Configuration.Server.Providers.Streaming.HttpStreamingProvider.GetConfig(String bucketName, String password)   at Couchbase.Core.ClusterController.CreateBucket(String bucketName, String password, IClusterCredentials credentials)}

If I switch to http://localhost:8091, it works fine.

Expected:

couchbase://localhost should be a valid connection string.
