Listing installed plugins is a sequential operation that iterates on each potential plugin binary under PACKER_PLUGIN_PATH. Each potential candidate may be executed in order to get its description, and to match that what is reported by the plugin binary matches what is effectively installed on the filesystem. This operation may be causing lots of I/O syncs, and if done sequentially on a rather large number of installed plugins will take time. In order to make this faster, we paralellise listing installations, so we run those commands in parallel in order to minimise idle waiting time on the main process.
