This adds a test to validate execs work with ArgsEscaped images. ArgsEscaped refers to a non-standard OCI image spec field that indicates that the command line for Windows Containers should be used from args[0] without escaping. This behavior comes into play with images that use a shell-form ENTRYPOINT or CMD in their Dockerfile. The behavior that the test is testing is that execs work properly with these images. Hcsshim prefers the commandline field on the OCI runtime spec and will ignore Args if this is filled in, which ArgsEscaped does. In Containerd/cri plugin the containers runtime spec is used as a base for the execs spec as well, so if commandline isn't cleared out then we'll end up launching the init process again instead of what the user requested.
