a2ef00c1b1 Add iptables restore failure metrics 
As mentioned in issue #80061, in iptables lock contention case,
we can see increasing rate of iptables restore failures because it
need to grab iptables file lock.

The failure metric can provide administrators more insight

Metrics will be collected in kube-proxy iptables and ipvs modes

a735c97356 kube-proxy: drop iptables version check 
Kube-proxy's iptables mode used to care whether utiliptables's
EnsureRule was able to use "iptables -C" or if it had to implement it
hackily using "iptables-save". But that became irrelevant when
kube-proxy was reimplemented using "iptables-restore", and no one ever
noticed. So remove that check.

90ce2d50d3 Add GetKernelVersion to ipvs.KernelHandler interface 
ipvs `getProxyMode` test fails on mac as `utilipvs.GetRequiredIPVSMods`
try to reach `/proc/sys/kernel/osrelease` to find version of the running
linux kernel. Linux kernel version is used to determine the list of required
kernel modules for ipvs.

Logic to determine kernel version is moved to GetKernelVersion
method in LinuxKernelHandler which implements ipvs.KernelHandler.
Mock KernelHandler is used in the test cases.

Read and parse file is converted to go function instead of execing cut.

proxy/ipvs: Compute all node ips only once when a zero cidr is used 
Computing all node ips twice would always happen when no node port
addresses were explicitly set. The GetNodeAddresses call would return
two zero cidrs (ipv4 and ipv6) and we would then retrieve all node IPs
twice because the loop wouldn't break after the first time.

Also, it is possible for the user to set explicit node port addresses
including both a zero and a non-zero cidr, but this wouldn't make sense
for nodeIPs since the zero cidr would already cause nodeIPs to include
all IPs on the node.

proxy/ipvs: Only compute node ip addresses once per sync 
Previously the same ip addresses would be computed for each nodePort
service and this could be CPU intensive for a large number of nodePort
services with a large number of ipaddresses on the node.

1dda3d8dfc kube-proxy: change buckets used by NetworkProgrammingLatency 
refs https://github.com/kubernetes/perf-tests/issues/640

We have too fine buckets granularity for lower latencies, at cost of the higher
latecies (7+ minutes). This is causing spikes in SLI calculated based on that
metrics.

I don't have strong opinion about actual values - those seemed to be better
matching our need. But let's have discussion about them.

Values:
