CloudBees Internal Ticket: [CTR-1444]
CloudBees SSH Build Agents Plugin intermittent SSH error since version 2.5 (CTR-1444)
The ChannelExec close without parameters was closing the underlying ssh channel connection synchronously in the CloudBees SSH Build Agents Plugin since version 2.5, making the connection unstable.
With this fix, ChannelExec is now closed asynchronously using close(false) instead of the closeable close method.
