Some charm builds will put additional functionality into a subdirectory of hooks/ (eg designate-bind creates a hooks/relations directory.) However, when running an action, those are run from "actions/pause" not as "hooks/config-changed". Which means that they cannot find the "relations" directory to import it. We could: a) symlink all the extra things from actions/* to point at hooks/* b) include hooks as part of the import path c) change so that all of those extra libraries are put into somewhere in 'lib' instead of somewhere in hooks/*. This patch chooses (b). This should fix: https://bugs.launchpad.net/charm-designate-bind/+bug/2107591 once it is rebuilt with this version of layer openstack.
