Remove config.ssh.timeout due to backward incompatibility with Vagrant 1.3.0
Remove config.ssh.timeout due to backward incompatibility with Vagrant 1.3.0

Vagrant 1.3.0 eliminated some configuration options, config.ssh.timeout being one of them.

Not going to replace with anything at the moment, we'll see if there is a need to set the general vm timeout at a later time.
