Description: 

When a socket timeout occurs with Client-Side Operation Timeout (CSOT) enabled, the session is not being marked as dirty as required. According to session's specification:

If a driver has a server session pool and a network error is encountered when executing any command with a ClientSession, the driver MUST mark the associated ServerSession as dirty.

Network error
Any network exception writing to or reading from a socket (e.g. a socket timeout or error).

 
Expected Behavior:
When CSOT is enabled and socket timeout occurs, the ServerSession should be marked as dirty upon encountering a network error.

Actual Behavior:
When CSOT is enabled and socket timeout occurs, the ServerSession is not marked as dirty.
