Add pseudo tty ability to ssh_command method

[Jesse Almanrode]

It would be handy to have a flag in the ssh_command method that would enable Paramiko's pseudo tty capability.

It would enable getting around this error:

sudo: sorry, you must have a tty to run sudo

Adding pseudo terminal creation to ssh_command method. It already existed for when output is combined.
