test spring-cleaning
This makes a quick pass through our tests;

Discard output/err
----------------------------------------------

Many tests were testing for error-conditions, but didn't discard output.
This produced a lot of noise when running the tests, and made it hard
to discover if there were actual failures, or if the output was expected.
For example:

    === RUN   TestConfigCreateErrors
    Error: "create" requires exactly 2 arguments.
    See 'create --help'.

    Usage:  create [OPTIONS] CONFIG file|- [flags]

    Create a config from a file or STDIN
    Error: "create" requires exactly 2 arguments.
    See 'create --help'.

    Usage:  create [OPTIONS] CONFIG file|- [flags]

    Create a config from a file or STDIN
    Error: error creating config
    --- PASS: TestConfigCreateErrors (0.00s)

And after discarding output:

    === RUN   TestConfigCreateErrors
    --- PASS: TestConfigCreateErrors (0.00s)

Use sub-tests where possible
----------------------------------------------

Some tests were already set-up to use test-tables, and even had a usable
name (or in some cases "error" to check for). Change them to actual sub-
tests. Same test as above, but now with sub-tests and output discarded:

    === RUN   TestConfigCreateErrors
    === RUN   TestConfigCreateErrors/requires_exactly_2_arguments
    === RUN   TestConfigCreateErrors/requires_exactly_2_arguments#01
    === RUN   TestConfigCreateErrors/error_creating_config
    --- PASS: TestConfigCreateErrors (0.00s)
        --- PASS: TestConfigCreateErrors/requires_exactly_2_arguments (0.00s)
        --- PASS: TestConfigCreateErrors/requires_exactly_2_arguments#01 (0.00s)
        --- PASS: TestConfigCreateErrors/error_creating_config (0.00s)
    PASS

It's not perfect in all cases (in the above, there's duplicate "expected"
errors, but Go conveniently adds "#01" for the duplicate). There's probably
also various tests I missed that could still use the same changes applied;
we can improve these in follow-ups.

Set cmd.Args to prevent test-failures
----------------------------------------------

When running tests from my IDE, it compiles the tests before running,
then executes the compiled binary to run the tests. Cobra doesn't like
that, because in that situation `os.Args` is taken as argument for the
command that's executed. The command that's tested now sees the test-
flags as arguments (`-test.v -test.run ..`), which causes various tests
to fail ("Command XYZ does not accept arguments").

    # compile the tests:
    go test -c -o foo.test

    # execute the test:
    ./foo.test -test.v -test.run TestFoo
    === RUN   TestFoo
    Error: "foo" accepts no arguments.

The Cobra maintainers ran into the same situation, and for their own
use have added a special case to ignore `os.Args` in these cases;
https://github.com/spf13/cobra/blob/v1.8.1/command.go#L1078-L1083

    args := c.args

    // Workaround FAIL with "go test -v" or "cobra.test -test.v", see #155
    if c.args == nil && filepath.Base(os.Args[0]) != "cobra.test" {
        args = os.Args[1:]
    }

Unfortunately, that exception is too specific (only checks for `cobra.test`),
so doesn't automatically fix the issue for other test-binaries. They did
provide a `cmd.SetArgs()` utility for this purpose
https://github.com/spf13/cobra/blob/v1.8.1/command.go#L276-L280

    // SetArgs sets arguments for the command. It is set to os.Args[1:] by default, if desired, can be overridden
    // particularly useful when testing.
    func (c *Command) SetArgs(a []string) {
        c.args = a
    }

And the fix is to explicitly set the command's args to an empty slice to
prevent Cobra from falling back to using `os.Args[1:]` as arguments.

    cmd := newSomeThingCommand()
    cmd.SetArgs([]string{})

Some tests already take this issue into account, and I updated some tests
for this, but there's likely many other ones that can use the same treatment.

Perhaps the Cobra maintainers would accept a contribution to make their
condition less specific and to look for binaries ending with a `.test`
suffix (which is what compiled binaries usually are named as).

remove unneeded "digest" alias for "go-digest"
This was there for historic reasons (I think `goimports` expected this,
and we used to have a linter that wanted it), but it's not needed, so
let's remove it (to make my IDE less complaining about unneeded aliases)

Derek McGowan 1fd2d66df8 Fix manifest lists to always use correct size
Stores complete OCI descriptor instead of digest and platform
fields. This includes the size which was getting lost by not
storing the original manifest bytes.

Attempt to support existing cached files, if not output
the filename with the incorrect content.

Kir Kolyshkin 6f8070deb2 Switch from x/net/context to context
Since go 1.7, "context" is a standard package. Since go 1.9,
x/net/context merely provides some types aliased to those in
the standard context package.

The changes were performed by the following script:

for f in $(git ls-files \*.go | grep -v ^vendor/); do
	sed -i 's|golang.org/x/net/context|context|' $f
	goimports -w $f
	for i in 1 2; do
		awk '/^$/ {e=1; next;}
			/\t"context"$/ {e=0;}
			{if (e) {print ""; e=0}; print;}' < $f > $f.new && \
				mv $f.new $f
		goimports -w $f
	done
done

[v2: do awk/goimports fixup twice]

Christy Perez 02719bdbb5 add manifest command
Enable inspection (aka "shallow pull") of images' manifest info, and
also the creation of manifest lists (aka "fat manifests").

The workflow for creating a manifest list will be:

`docker manifest create new-list-ref-name image-ref [image-ref...]`
`docker manifest annotate new-list-ref-name image-ref --os linux --arch
arm`
`docker manifest push new-list-ref-name`

The annotate step is optional. Most architectures are fine by default.

There is also a `manifest inspect` command to allow for a "shallow pull"
of an image's manifest: `docker manifest inspect
manifest-or-manifest_list`.

To be more in line with the existing external manifest tool, there is
also a `-v` option for inspect that will show information depending on
what the reference maps to (list or single manifest).
