Add `IAsyncConfigureOptions` to allow configuring options asyncronosly

Is your feature request related to a problem? Please describe the problem.

I am using OrchardCore CMS as a SaaS solution to support multi-tenants.

Configuring options in OrchardCore is typically done by doing a database lookup (Single lookup per tenant per startup). After the single lookup, we read the same object from memory so the 2+ calls to configure options will not block the main thread but the first one does.

When you have many tenants and a frequent tenant reload/startup, this cause a frequent block that affect requests made to other tenants.

Six years ago similar request was denied without real explanation of why not dotnet/aspnetcore#2381 so the reason why not is not clear.

Describe the solution you'd like

I think there is a need to IConfigureOptionsAsync<> to allow us to configure options asynchronously and eliminate the need to block the main thread while trying to configure the options.

I appreciate the issue but it’s this isn’t possible with the existing options design. You need everything to be async so this proposal needs to be more fleshed out.

Can you please shed some light on the reasons for closing this so quickly? Especially after dotnet/aspnetcore#2381 was closed without explanation. Surely, it needs design (but so does every feature request I guess) and yes, everything using this needs to be async, but that's kind of the point. We're forced to do sync-over-async currently, which is less than ideal.

It’s fine to leave it open @tarekgh.
