[ct_netconfc] Start multiple sessions per SSH connection

The following new functions are added to ct_netconfc:

* connect/1,2 - open an SSH connection to a netconf server
* disconnect/1 - close the given SSH connectoin
* session/1,2,3 - open an SSH channel on the give connection and send
  'hello' to start a netconf session.

This allows running multiple channels on on SSH connection, realizing
one netconf session per channel. The existing ct_netconfc:open will
always run one channel(session) per SSH connection.
