RFR: 8308565: HttpClient: Sanitize logging while stopping

Mon May 22 15:54:08 UTC 2023

When the HttpClient is stopping many exception stack traces may be logged, in particular if the Http2Connection attempts to send a GOAWAY frame after the underlying TCP connection or the selector have been closed.

The Http2Connection should look at the Http2ClientImpl state before logging the exception as an error. If the Http2ClientImpl is stopping, a simple debug message should be enough.
