/** Start tearing down a `net::ssl::stream`.
This begins tearing down a connection asynchronously.
The implementation will call the overload of this function
based on the `Stream` parameter used to consruct the socket.
When `Stream` is a user defined type, and not a
`net::ip::tcp::socket` or any `net::ssl::stream`,
callers are responsible for providing a suitable overload
of this function.
@param role The role of the local endpoint
@param stream The stream to tear down.
@param handler The completion handler to invoke when the operation
completes. The implementation takes ownership of the handler by
performing a decay-copy. The equivalent function signature of
the handler must be:
@code
void handler(
error_code const& error // result of operation
);
@endcode
Regardless of whether the asynchronous operation completes
immediately or not, the handler will not be invoked from within
this function. Invocation of the handler will be performed in a
manner equivalent to using `net::post`.
@par Per-Operation Cancellation
This asynchronous operation supports cancellation for the following
net::cancellation_type values:
@li @c net::cancellation_type::terminal
@li @c net::cancellation_type::partial
@li @c net::cancellation_type::total
if they are also supported by the socket's @c async_teardown
and @c async_shutdown operation.
