bugfix: ARSN-4 rework KMIP connection handling

Rework KMIP connection handling to catch all errors, including before
the connection is established, and return the error to each pending
command response.

In particular, setup the 'error' listener (also 'data' and 'end'
listeners) as soon as the TLS client socket is created instead of
waiting for the connection to be established to set the listeners.
