The existing gate partitioned a disk for use with docker, depending on the gate it would use the swap disk (RAX) or a spare disk (HP). However, with the new gates (Bluebox + OVH) there is neither a spare disk nor a swap disk. This leaves us with one choice: File based loop device. This patch creates a file at /swapfile to ensure we have swap. It creates a file at /docker to ensure we have a loop device for Docker. Right now the /docker file is 10GB and the /swapfile is 4GB due to size limitations in the gate across all servers and types. This has proven to be enough space for all our current tests. Additionally, reduce the number of threads the gate uses to 4 to prevent the lockup and hour timeout we have been seeing as more recently in the gate. The scripts that setup the gate are moved to the tools directory rather than the tests directory to match the structure of the other projects.
