[ Merge of http://go/wvgerrit/21960 ] When an offline release message is generated, a session is created internally to generate the release and handle the release response. If the response is never provided (network, server errors), or there is an error when the response is being processed, the session may not be closed. This change introduces a time to live for release sessions of 60 seconds and will be reclaimed after this period.
