Add a test to detect if the main disk is a SSD.

Add a test to detect if the main disk is a SSD.

It uses "hdparm -I" to check. However, it is not 100% sure if the device doesn't report the rotation rate.

Seems fine, assuming ericli's fix precompiles deps as well as tests?

If not, might be better to add the binary to the test image.

I don't think the precompiled deps issue is resolved yet -- this is his
workaround for storage_Fio:

    def run_once(self):
        # TODO(ericli): need to find a general solution to install dep packages
        # when tests are pre-compiled, so setup() is not called from client any
        # more.
        dep = 'libaio'
        dep_dir = os.path.join(self.autodir, 'deps', dep)
        self.job.install_pkg(dep, 'dep', dep_dir)

Yeah, you need a similar code snippet to setup deps.

Also please take a look at site_tests/setup/control to see how to include this
tests into pre-compilation.
