[AL:
rebased on current master
merged into single function for generic cgroups
]
Signed-off-by: Aaron Lauterer <a.laute...@proxmox.com>

Notes:
while the read_cgroup_pressure function would fit better into
SysFSTools.pm I have kept it in ProcFSTools.pm for now, mainly because
we currently don't use ProcFSTools in SysFSTools, and the actual
function to parse the contents of the pressure files in in ProcFSTools.
If that would not be an issue, we could also move the
read_cgroup_pressure function to SysFSTools
changes since
RFC:
* instead of dedicated functions for CTs and VMs we use a more generic
for cgroups in general
