PR #22 merged an upgrade to PyYAML which broke our existing use of
yaml.load for configuration and state files.
Unfortunately, we can't use safe_load here because we make use of
defaultdict
datastructures that don't work with this method:So this PR explicitly uses the UnsafeLoader to load the config and state
files.
This should be fine, as we're not accepting any arbitrary data
from untrusted users for this configuration. Anyone who is using this
tool has Docker access, so should be assumed to be an administrator
anyway.
