This refactoring reversed the order of the "ParentDirectories" function: ffc372a63b (diff-d36eb675aa49a7b471e3a2be77005b18R465)
As a side-effect, parent directories weren't added in lexicographical
order, which broke some tests. We now ensure in unit test that the order
of the ParentDirectories function is stable.
The zero value of time.Time is not a valid argument to os.Chtimes
because of the syscall that os.Chtimes calls. Instead we update the zero
value of time.Time to the zero value of Unix Epoch
Add a new option additonal-whitelist which defaults
to a single entry, "/var/run". This will allow users to
remove "/var/run" from the whitelist or retain the current
behavior with no change.
Previously kaniko would compute the cache key for any copy command by computing
the combined hash of all files in a directory, even if they were listed
as ignored.
With this change, the cache key creation was updated to be aware of ignored
files.

Certain utilities like Apt depend on modtime
for certain files. Kaniko was not setting modtime when
extracting files and so this broke things like apt.
Kaniko now sets the file mod time to the value from the tar
header.
Update caching run and copy commands to use the new
GetFSFromLayers method and include the whiteout option so that
whiteout files are extracted and included in extractedFiles
* add util.GetFSFromLayers
* GetFSFromImage delegates to GetFSFromLayers
* add FSOpts and FSConfig for GetFSFromLayers
* add tests for GetFSFromLayers
* add gomock for test support
* add mock_v1 for layers
When using the COPY command, if the source and destination have the same
the file should be skipped rather than copied. This is to prevent the
file from being overwritten and therefore producing an empty file.
