tests: Restructure tests directory

All unit tests go in the `unit` subdirectory. These are tests which
should gate a release of Seastar, or prevent a branch from merging. They
can be run automatically and without human supervision.

All performance tests go in the `perf` subdirectory.

Application-specific tests move to the application-specific subdirectory
in `apps`.

Small tests which demonstrate or validate functionality of Seastar but
which require human intervention have been moved to the `demos`
directory.
