Fix urls for root domains

[Pralish]

We are familiar with the fact that we need to pass host and/or subdomain parameters in url helper for it to work properly, especially for asset urls.

And we were passing either Subdomain.current.hostname or Apartment::Tenant.current as the subdomain, which is not consistent. Subdomain.current.hostname returns nil for root domain, which is fine, but Apartment::Tenant.current returns 'public' which causes all the asset urls to be prefixed with 'public'

rails_blob_url(attachment, subdomain: Apartment::Tenant.current, subdomain: Apartment::Tenant.current)

Issue: #1537

With this PR, we will no longer have to pass host and subdomain value to url helper. They are set by default based on the request host.

rails_blob_url(attachment)

You can pass the host and subdomain parameters if you want to override the default value

@Pralish I see the API surface for URL's and asset linking as changed, could you write some documentation to include as part of the release for server engineers to use as reference?
