Some of the unit tests cannot pass on Windows due to various reasons:
- fsnotify does not have a Windows implementation.
- Proxy Mode IPVS not supported on Windows.
- Seccomp not supported on Windows.
- VolumeMode=Block is not supported on Windows.
- iSCSI volumes are mounted differently on Windows, and iscsiadm is a
Linux utility.
This commit adds the framework for the new local detection
modes BridgeInterface and InterfaceNamePrefix to work.

We were detecting the IP family that kube-proxy should use
based on the bind address, however, this is not valid when
using an unspecified address, because on those cases
kube-proxy adopts the IP family of the address reported
in the Node API object.
The IP family will be determined by the nodeIP used by the proxier
The order of precedence is:
1. config.bindAddress if bindAddress is not 0.0.0.0 or ::
2. the primary IP from the Node object, if set
3. if no IP is found it defaults to 127.0.0.1 and IPv4

Removed unneeded comments
Matched style from other PR's
Only print error when lenient decoding is successful

Cleanup TODO's and tests
Add explicit newline for appended config
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.
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.
These are based on recommendation from
[staticcheck](http://staticcheck.io/).
- Removes dead type/function along with the import that the function
introduced.
- Removes unused struct fields.
- Removes select nested in a tight for loop, the select does not have a
default, so it will be blocking.

When kube-proxy was refactored to use a configuration file, the ability
to use 0 for conntrack min, max, max per core, and tcp timeouts was
inadvertently broken; if you specified 0, it would instead apply the
default value from defaults.go.
This change restores the ability to use 0 to mean 0.
