Framework for extended integration tests 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.

# Crosvm Integration Tests
docs: Use mdformat to format markdown files The tool is added to ./tools/fmt which will be called during ./tools/presubmit as well as by Kokoro during testing. This requires a new dev container version to bundle the mdformat tool in the container. Note: mdformat does not have any IDE integrations, but the prettier plugin with prose-wrap enabled and a line length of 100 provides almost identical results.

These tests run a crosvm VM on the host to verify end to end behavior. They use a prebuilt guest
kernel and rootfs, which is downloaded from google cloud storage.

If the test needs to run offline, or you want to make changes to the kernel or rootfs, you have to
specify the environment variables `CROSVM_CARGO_TEST_KERNEL_BINARY` and
`CROSVM_CARGO_TEST_ROOTFS_IMAGE` to point to the right files.

Then run the upload script to build and upload the new prebuilts. **Never** try to modify an
existing prebuilt as the new images may break tests in older versions.
