This is a wrapper for socket.connect(addr), when addr is not accessible
from the local machine. It simply creates an ssh tunnel using the remaining args,
and calls socket.connect('tcp://localhost:lport') where lport is the randomly
selected local port of the tunnel.

on this machine to localhost:rport on server. The tunnel
will automatically close when not in use, remaining open
for a minimum of timeout seconds for an initial connection.
This creates a tunnel redirecting `localhost:lport` to `remoteip:rport`,
as seen from `server`.
keyfile and password may be specified, but ssh config is checked for defaults.
Parameters
----------
lport : int
local port for connecting to the tunnel from this machine.
rport : int
port on the remote machine to connect to.
server : str
The ssh server to connect to. The full ssh server string will be parsed.
user@server:port
remoteip : str [Default: 127.0.0.1]
The remote ip, specifying the destination of the tunnel.
Default is localhost, which means that the tunnel would redirect
localhost:lport on this machine to localhost:rport on the *server*.
keyfile : str; path to public key file
This specifies a key to be used in ssh login, default None.
Regular default ssh keys will be used without specifying this argument.
password : str;
Your ssh password to the ssh server. Note that if this is left None,
you will be prompted for it if passwordless key based login is unavailable.
timeout : int [default: 60]
The time (in seconds) after which no activity will result in the tunnel
closing. This prevents orphaned tunnels from running forever.

when shell ssh is unavailable (e.g. Windows).
This creates a tunnel redirecting `localhost:lport` to `remoteip:rport`,
as seen from `server`.
If you are familiar with ssh tunnels, this creates the tunnel:
ssh server -L localhost:lport:remoteip:rport
keyfile and password may be specified, but ssh config is checked for defaults.
Parameters
----------
lport : int
local port for connecting to the tunnel from this machine.
rport : int
port on the remote machine to connect to.
server : str
The ssh server to connect to. The full ssh server string will be parsed.
user@server:port
remoteip : str [Default: 127.0.0.1]
The remote ip, specifying the destination of the tunnel.
Default is localhost, which means that the tunnel would redirect
localhost:lport on this machine to localhost:rport on the *server*.
keyfile : str; path to public key file
This specifies a key to be used in ssh login, default None.
Regular default ssh keys will be used without specifying this argument.
password : str;
Your ssh password to the ssh server. Note that if this is left None,
you will be prompted for it if passwordless key based login is unavailable.
timeout : int [default: 60]
The time (in seconds) after which no activity will result in the tunnel
closing. This prevents orphaned tunnels from running forever.
