When updating the inventory, write to a temp file and replace the original once writing is complete, to allow for an atomic replacement of the contents. Ensures that ansible reading an inventory file will get either the old or new contents, but never the truncated version of the file that appears should you open it with 'w' mode set to replace the contents. Solves the 'provided hosts list is empty' error, which is emitted by ansible should it manage to be reading the inventory file just as it was truncated, but before the new contents were flushed to disk. Partially-Fixes: #6526
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.
