Tests are short-lived and use a small amount of data. They are also often run repeatly, and the data is deleted immediately after the test. This is a good scenario for using the kernel page cache, as it can cache read-only data from test to test, and avoid spilling write data to disk if it is deleted quickly. Acknowledge this by using the new --kernel-page-cache option for tests. This is expected to help on large machines, where the disk can be overloaded. Smaller machines with NVMe disks probably will not see a difference. Closes #8347
