This CL expands the existing boot.rs test to not just boot a kernel but also provide a debian-based rootfs and a special init binary that is used to communicate between test code and the guest VM. The delegate binary listens for commands on /dev/ttyS1 and returns the stdout of the executed command. This allows the test code to setup pipes for the serial device to issue commands in the client and receive the command output, which provides a good foundation for tests of basic functionality without the need to pass test binary code into the guest. The integration tests will pull a prebuilt kernel and rootfs image from cloud storage unless local files are specified via ENV variables. The integration_tests/guest_under_test directory contains the files needed to build and upload those prebuilts. BUG=b:172926609 TEST=This is a test.
