RelocatableSysFs allows to consume a sysfs tree whose root is not `/sys`. this means we can easily consume a syfs snapshot from another node, for troubleshoot and debugging purposes, without complex/cumbersome chroot dances or even more complicated, without containerizing the test session. the cadvisor's SysFS interface is not formalized nor very clean, so we add the prefix in few key place discovered using tests and reviewing how the API is used.
