The overlay filesystem does not support inotify at this time. The
resolv.conf updater test was passing on overlay-based Jenkins because of
a fluke--because it was DIND, /etc/resolv.conf on the "host" was really
a bind-mounted resolv.conf from the outer container, which means a watch
directly on that file worked as it was not overlay backed. The new test
(from #10703) unmounts the bind-mounted copy to test create and modify
code-paths, which caused us to hit the issue.
This PR also adds a note to the docs about the lack of auto-update when
using the overlay storage driver.
See https://lkml.org/lkml/2012/2/28/223 for more info on inotify and
overlay.

Some pull/push tests are launching `registry-v2`
binary which is compiled and installed if the tests
are running in-container through `make test-integration-cli`.
However, registry is not supported to run on non-linux
platforms and we can't really spin up any registry-v2
containers in the remote DOCKER_TEST_HOST at this point.
Just skipping those with the new TestRequirement called
`RegistryHosting`.

Skip tests based on remote daemon's exec support (to exclude
these tests from `make test` ran in LXC case). Makes use of
`test_no_exec` build tag passed by build scripts.

Skipping some of the tests closely tied to running in a
unix environment. Windows does not support chmod/chown
and this causes some tests to fail creating desired
behavior.
- `TestBuildWithInaccessibleFilesInContext`: uses chown/chmod
- `TestBuildDockerfileOutsideContext`: uses os.Symlink, not implemented on
windows
- `TestCpUnprivilegedUser`: uses chmod, and requires 'unprivilegeduser'
created by Dockerfile (and thus requires to run inside container)
- `TestBuildChownSingleFile`: uses chown

If DOCKER_CLIENTONLY is set for test-integration-cli, we don't set
the 'daemon' build tag. 'isRemoteDaemon' will help us skip such
tests without a need to move them to a separate file and accidentally
lose track of them.
Added `testRequires` function to skip tests based on predefined
conditions evaluated in runtime. This way we can easily extend test
requirements like:
testRequires(t, Networking, SameHostDaemon, Linux)
