Prior to this commit, if Windows was slow to reboot, Vagrant would fail to find the right IP address to upload the wait_for_reboot script to. This commit fixes this race condition by adding a timeout to ensure that Vagrant can retry. It also properly catches an exception in the winrm ready? method for checking if a guest is properly ready for communications.
Vagrant Core Plugins
These are plugins that ship with Vagrant. Vagrant core uses its own plugin system to power a lot of the core pieces that ship with Vagrant. Each plugin will have its own README which explains its specific role.
