Add non-async version of connect_with_connector

Motivation

I am using tonic with a custom transport protocol, so I am using connect_with_connector. However, my connector does not need to await anything, so I would like a version of connect_with_connector that is not async fn.

Proposal

Add a method on tonic::transport::Endpoint like pub fn connect_with_connector<C>(&self, connector: C) -> Result<Channel, Error>, emphasis on the non-async part. This would follow how the default transport (TCP) has async fn connect and fn connect_lazy.

Alternatives

My custom transport is also infallible, so another option could be pub fn connect_with_connector_connected<C>(&self, connector: C) -> Channel where C: ... and ... is a non-future type for converting Uri to Channel.
