be4b7176dc Fix Abs path validation on Windows (#124084) 
* Windows: Consider slash-prefixed paths as absolute

filepath.IsAbs does not consider "/" or "\" as absolute paths, even
though files can be addressed as such. [1][2]

Currently, there are some unit tests that are failing on Windows due to
this reason.

6dbc754ed6 Retool typecheck to be simpler 
Instead of walking paths ourselves, just let Go's packages library do
it.  This is a slight CLI change - it wants "./foo" rather than "foo".

This also flagged a few things which seem to be legit failures.

c65d9e4d59 Replaces path.Operation with filepath.Operation 
The path module has a few different functions:
Clean, Split, Join, Ext, Dir, Base, IsAbs. These functions do not
take into account the OS-specific path separator, meaning that they
won't behave as intended on Windows.

For example, Dir is supposed to return all but the last element of the
path. For the path "C:\some\dir\somewhere", it is supposed to return
"C:\some\dir\", however, it returns ".".

Instead of these functions, the ones in filepath should be used instead.

c1ce1e00ee Properly build-tag the Linux kube-proxy backend code 
This had to be able to build on OS X before to make verify-typecheck
pass, but now that that's fixed we can tag the code properly as being
linux-only.

b4d1440063 unittests: Fixes hostutil.GetFileType for Windows 
GetFileType is meant to return the type of the given file by using os.Stat.
However, os.Stat doesn't work on Windows for Unix Sockets, causing an error to occur:

[2-Socket Test] unexpected error :
CreateFile C:\Users\Administrator\AppData\Local\Temp\test-get-filetype-2776877299\mt.sock:
The file cannot be accessed by the system.

This is a known issue and we're already using a workaround for this in
pkg/kubelet/util/util_windows.go.

This commit fixes this issue for GetFileType on Windows.

d38ac7e7c6 Replace os.Setenv with testing.T.Setenv in tests 
T.Setenv ensures that the environment is returned to its prior state
when the test ends. It also panics when called from a parallel test to
prevent racy test interdependencies.

4381973a44 Revert (most of) "Issue 70020; Flush Conntrack entities for SCTP" 
This commit did not actually work; in between when it was first
written and tested, and when it merged, the code in
pkg/proxy/endpoints.go was changed to only add UDP endpoints to the
"stale endpoints"/"stale services" lists, and so checking for "either
UDP or SCTP" rather than just UDP when processing those lists had no
effect.

This reverts most of commit aa8521df66
(but leaves the changes related to
ipvs.IsRsGracefulTerminationNeeded() since that actually did have the
effect it meant to have).

4f75949bcb Ipvs: Add a new FlagSourceHash to "mh" distribution method. 
With the flag, ipvs uses both source IP and source port (instead of
only source IP) to distribute new connections evently to endpoints
that avoids sending all connections from the same client (i.e. same
source IP) to one single endpoint.

User can explicitly set sessionAffinity in service spec to keep all
connections from a source IP to end up on the same endpoint if needed.
