The download manager assumed there was at least one layer involved in
all images. This can be false if the image is essentially a copy of
`scratch`.
Fix a nil pointer dereference that happened in this case. Add
integration tests that involve schema1 and schema2 manifests.
Fixes#21213

Following #19995 and #17409 this PR enables skipping userns re-mapping
when creating a container (or when executing a command). Thus, enabling
privileged containers running side by side with userns remapped
containers.
The feature is enabled by specifying ```--userns:host```, which will not
remapped the user if userns are applied. If this flag is not specified,
the existing behavior (which blocks specific privileged operation)
remains.

If the destination does not exist, it needs to be created with ownership
mapping to the remapped uid/gid ranges if user namespaces are enabled.
This fixes ADD operations, similar to the prior fixes for COPY and WORKDIR.

This PR adds the "notary" binary requirement for tests.
Previously, NotaryHosting was checking for the "notary-server"
binary under the name notaryBinary. This renames that reference to
notaryServerBinary, so that notaryBinary can rightly refer
to the actual "notary" binary.
Currently only one test actually uses the notary binary, so it's been
updated accordingly.

Fixes a bug when the log output is empty.
The length of a slice containing an empty string is 1, not 0, so
the test fails to catch when the log is empty. Instead, take a look at
out, which is just a string.

Docker creates a UTS namespace by default, even with --net=host, so it
is reasonable to let the user set the hostname. Note that --hostname is
forbidden if the user specifies --uts=host.

Update unit test and documentation to handle the new case where Username
is set to <token> to indicate an identity token is involved.
Change the "Password" field in communications with the credential helper
to "Secret" to make clear it has a more generic purpose.

On redhat based distribution, checking that USER_NS is compiled in the
kernel is not sufficient, we also have to check that the feature as
been enabled.
With this commit, it is now done by checking the content of
`/sys/module/user_namespace/parameters/enable`.
