S3A: S3AInputStream doesn't recover from HTTP/channel exceptions

S3AInputStream doesn't seem to recover from Http exceptions raised through HttpClient or through OpenSSL.

• review the recovery code to make sure it is retrying enough, it looks suspiciously like it doesn't
• detect the relevant openssl, shaded httpclient and unshaded httpclient exceptions, map to a standard one and treat as comms error in our retry policy

This is not the same as the load balancer/proxy returning 443/444 which we map to AWSNoResponseException. We can't reuse that as it expects to be created from an software.amazon.awssdk.awscore.exception.AwsServiceException exception with the relevant fields...changing it could potentially be incompatible.
