Change subject: KUDU-2135 (part 1): add persistent disk states ...................................................................... KUDU-2135 (part 1): add persistent disk states This patch introduces a new format for PathInstanceMetadataFiles that includes a disk health and path for each data directory, and a timestamp that the path instance file was last updated. These additions will be necessary to ensure failed disks will not be used and that data is where expect it to be (which will be increasingly important as we begin to supporting removal/addition/replacement of disks). The expected usage of the new format would enforce startup restrictions on the server (e.g. to not use a failed disk, to not use data if it is on a different disk than expected, etc.) and tooling does not yet exist to work around these restrictions. As such, this patch will upgrade and maintain the new path sets as necessary, persisting disk health when disks fail, but will not apply the mentioned restrictions at startup. A test is added to data_dirs-test to ensure the path instance files get updated/upgraded appropriately.
