Blazor-wasm (authentication): add OidcProviderOptions.MetadataAddress property

[vstribrny]

While using builder.Services.AddOidcAuthentication (as part of WebAssemblyAuthenticationServiceCollectionExtensions), I am not able to specify metadata address of the OIDC provider. The metadata endpoint does not necessarily have to be aligned with OidcProviderOptions.Authority (typical in dev/test environments, but sometimes also in prod ones).

I think we need to add MetadataAddress property to OidcProviderOptions (much like there is Microsoft.AspNetCore.Authentication.OpenIdConnect.MetadataAddress in server-side OIDC configuration).

Or, am I missing something and it is somehow possible to configure metadata address if OIDC provider?

@vstribrny thanks for contacting us.

Is there any specific provider you are running into issues with?

The OIDC provider is IdentityServer, our custom implementation.
