a1f73cc247 ReservedMemory Configuration for NUMA 
Kubelet throws error when multiple numa nodes are specified for memory
reservation. This is due to "," being used as separator for different
memory types within same numa node as well as for different numa nodes.

This PR fixes the error by using ";" as the separator for
specifying multiple numa node configuration.

7223f12f39 don´t leak files on iptables tests 
the iptables restore function, if it considers that the --wait flag
is not supported, creates a lock file to mimic the iptables behaviour.

The test should take this into account and remove the file.

7561a0f96e memory manager: provide new flag var to parse reserved-memory parameter 
The new flag will parse the `--reserved-memory` flag straight forward
to the []kubeletconfig.MemoryReservation variable instead of parsing
it to the middle map representation.

It gives us possibility to get rid of a lot of unneeded code and use the single
presentation for the reserved-memory.

4d30435f24 ipset: Address a TODO, add test for netmask 
This PR removes a TODO comment by adding some netmask tests. The TODO comment
introduced by commit e768924a62 "validate entry in ipset".

// TODO: CIDR /32 may not be valid

The comment says that 32 is invalid netmask, but in reality values ​​from 0 to
32 are valid because the result of the Linux ipset command says so.

$ sudo ipset create foo hash:ip,port,net
$ sudo ipset add foo 10.20.30.40,53,192.168.3.1/33
ipset v7.5: Syntax error: '33' is out of range 0-32
$ sudo ipset --version

924553b7ee iptables don't do reverse DNS lookups 
the iptables monitor was using iptables -L to list the chains,
without the -n option, so it was trying to do reverse DNS lookups.
A side effect is that it was holding the lock, so other components
could not use it.
We can use -S instead of -L -n to avoid this, since we only want
to check the chain exists.

kubelet: Avoid sending no-op patches 
In an e2e run, out of 1857 pod status updates executed by the
Kubelet 453 (25%) were no-ops - they only contained the UID of
the pod and no status changes. If the patch is a no-op we can
avoid invoking the server and continue.

Be more agressive acquiring the iptables lock 
iptables has two options to modify the behaviour trying to
acquire the lock.

--wait  -w [seconds]    maximum wait to acquire xtables lock
                        before give up
--wait-interval -W [usecs]  wait time to try to acquire xtables
                            lock
                            interval to wait for xtables lock
                            default is 1 second

Kubernetes uses -w 5 that means that wait 5 seconds to try to
acquire the lock. If we are not able to acquire it, kube-proxy
fails and retries in 30 seconds, that is an important penalty
on sensitive applications.
We can be a bit more aggresive and try to acquire the lock every
100 msec, that means that we have to fail 50 times to not being
able to succeed.

Remove pkg/util/mount (moved out of tree) 
This patch removes pkg/util/mount completely, and replaces it with the
mount package now located at k8s.io/utils/mount. The code found at
k8s.io/utils/mount was moved there from pkg/util/mount, so the code is
identical, just no longer in-tree to k/k.

Retire mount.Exec for k8s.io/utils/exec 
This patch removes mount.Exec entirely and instead uses the common
utility from k8s.io/utils/exec.

The fake exec implementation found in k8s.io/utils/exec differs a bit
than mount.Exec, with the ability to pre-script expected calls to
Command.CombinedOutput(), so tests that previously relied on a callback
mechanism to produce specific output have been updated to use that
mechanism.

Move mount/fake.go to mount/fake_mount.go 
This patch moves fake.go to mount_fake.go, and follows to principle of
always returning a discrete type rather than an Interface. All callers
of "FakeMounter" are changed to instead use "NewFakeMounter()". The
FakeMounter "Log" struct member is changed to not be exported, and
instead only access through a new "GetLog()" method.
