add root_disk threshold detection (#12259) as there is no automatic way to detect if there is a root disk mounted on / or /var for the container environments due to how the root disk information is masked inside overlay root inside container. this PR brings an environment variable to set root disk size threshold manually to detect the root disks in such situations. 2021-05-08 18:40:29 -04:00			`-----BEGIN CERTIFICATE-----`
