The new class is responsible for actually running the tests and
processing their results. This commit also adds a decorator function for
adding new tests. No automatic test discovery, at least yet.

The new class will be used as an abstract base class for build
performance tests. This implementation contains some common
functionality used in multiple tests, "copied" from the
build-perf-test.sh shell script.

Add a new utility class for dropping Linux kernel caches. It uses sudo
and tee to write to the drop_caches file. Checking if the user has the
permissions to drop caches (without a password) is done by trying to
writing an invalid value to the drop_caches file. This way, we will find
if writing (with tee) is possible but not really dropping caches, yet.
User can avoid giving the password by adding something like:
<user> ALL = NOPASSWD: /usr/bin/tee /proc/sys/vm/drop_caches
to the system sudoers file.
