Can the err var above be put into the function scope so it can be part of this error message? That will help with debugging

Can we do something like:
n.clientMutex.RLock()
client_ready := n.client != nil
n.clientMutex.RUnlock()
if !client_ready {
n.clientMutex.Lock()
n.connect()
n.clientMutex.Unlock()
}and get rid of the else branch and second n.clientMutex.RUnlock() call entirely?

Are we sure that every possible error returned from NewSession() requires a Close() and connect() ?

This PR is WIP.
This PR makes it possible to reuse a client connection and open multiple sessions. This saves time.
