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.
