> We should add the ability to specify a custom cgroup path. This is how the documentation
of {{linux-container-executor.cgroups.mount-path}} would look like:
> {noformat}
>     Requested cgroup mount path. Yarn has built in functionality to discover
>     the system cgroup mount paths, so use this setting only, if the discovery does not
work.
>     This path must exist before the NodeManager is launched.
>     The location can vary depending on the Linux distribution in use.
>     Common locations include /sys/fs/cgroup and /cgroup.
>     If cgroups are not mounted, set yarn.nodemanager.linux-container-executor.cgroups.mount
>     to true. In this case it specifies, where the LCE should attempt to mount cgroups
if not found.
>     If cgroups is accessible through lxcfs or some other file system,
>     then set this path and yarn.nodemanager.linux-container-executor.cgroups.mount to
false.
>     Yarn tries to use this path first, before any cgroup mount point discovery.
>     If it cannot find this directory, it falls back to searching for cgroup mount points
in the system.
>     Only used when the LCE resources handler is set to the CgroupsLCEResourcesHandler
> {noformat}
