1. Fixing connection cleanup in case of mass connection breaking. …

    CAUSE:
    In some cases when credentials expire, or servers encounters a
    blip and closes all connections. The driver gets close message on all
    connections. While processing those close messages, the driver was
    getting into race conditions, where in multiple threads were trying to
    close connections and trying to update the connections object i.e. list
    of connections in the pool. This was leading to uncaught exceptions and
    stale connections in the pool. These connections are never cleanedup
    post this.
   
    FIX:
    Iterate the connections list while creating the connectionPool Info.
    Since the list used is copyOnWrite, the iterator API creates a clone
    and uses that clone for referring the element. Thus providing thread
    safe interface.
   
    However the information provided by this iteration is a bit stale, but
    this doesn't matter.
