Removing security/py-ssh

[Guillaume Lasmayous <netbsd-lists%guigui2.net@localhost>]

Hello,

I'd like to remove security/py-ssh in the coming days.
I committed it when it was a dependency for sysutils/fabric.
Now that fabric has moved back to using security/py-paramiko, I don't see
any reason to keep py-ssh around.

Any objections to removing it ?

Thanks,
G.
