Run the specific quirks handler, the follow handlers are supported:
- PreCacheOpen: run *before* the apt cache is opened the first time
to set options that affect the cache
- PostInitialUpdate: run *before* the sources.list is rewritten but
after an initial apt-get update
- PreDistUpgradeCache: run *right before* the dist-upgrade is
calculated in the cache
- PostDistUpgradeCache: run *after* the dist-upgrade was calculated
in the cache
- StartUpgrade: before the first package gets installed (but the
download is finished)
- PostUpgrade: run *after* the upgrade is finished successfully and
packages got installed
- PostCleanup: run *after* the cleanup (orphaned etc) is finished
