Add autopkgtest policy

Add new autopkgtest policy: it determines the autopkgtests for a
source package (its own, direct reverse binary dependencies, and
Testsuite-Triggers), requests tests via AMQP, fetches results from swift, and
keeps track of pending tests between run. This also caches the downloaded
results from swift, as re-dowloading them all is very expensive.

This introduces two new hints:

 * force-badtest pkg/ver[/arch]: Failing results for that package will be
   ignored. This is useful to deal with broken tests that get imported from
   Debian or are from under-maintained packages, or broke due to some
   infrastructure changes. These are long-lived usually.

 * force-skiptest pkg/ver: Test results *triggered by* that package (i. e.
   reverse dependencies) will be ignored. This is mostly useful for landing
   packages that trigger a huge amount of tests (glibc, perl) where some tests
   are just too flaky to get them all passing, and one just wants to land it
   after the remaining failures have been checked. This should be used rarely
   and the hints should be removed immediately again.

Add integration tests that call britney in various scenarios on constructed
fake archives, with mocked AMQP and Swift results.
