* refactor `SubscriptionClosed`

I noticed that we "trying" to sending "close messages" on subscriptions
that already has been terminated by the client which is unnecessary.

Moreover, this introduces `fn is_closed` to check whether a given
channel is closed without having to send an actual message on the channel.

Closes https://github.com/paritytech/jsonrpsee/issues/448

This PR adds an implementation for `SubscriptionClient` to the `HttpClient` struct, which makes it possible for http clients to use macro-generated RPC servers. If an http client tries to set up a subscription it will fail with a `HttpNotImplemented` error.
