options:
-n | --dry-run pass dry-run to clean-region-obsolete

--no-redirect do not redirect output to results dir
Calls clean-region-obsolete with inforation in 'config'. Where
config is like the following:
# number-published keep-private-for-days region regex-for-manifest
5 60 us-east-1 ^ubuntu-images-testing-us/ubuntu-karmic-daily-amd64
The above example will keep 5 public builds, and keep builds private
for 60 days before deletion. For manifests that match the given
regex
if 'region' is "all", then loop over ${ALL_REGIONS}
regex will have the following substituions done:
- %{a} : arch (i386 or x86_64)
- %{r} : region (${ALL_REGIONS})
- %{l} : location (region, except for us-east-1:us, eu-west-1:eu)
