rootDisk on containers can have different device Id

[harshavardhana]

Description

rootDisk on containers can have different device Id

Motivation and Context

use /etc/hosts instead of / to check for common
device id, if the device is the same for /etc/hosts
and the --bind mount to detect root disks.

Bonus enhance healthcheck logging by adding maintenance
tags, for all messages.

How to test this PR?

Test with mounted disks with one of them being root partition
