This was required because previously the hashing was python session dependent, meaning sequential charm calls generated different hash values for the same inputs. The cert_handler recently received a similar fix, but it removed the refresh_events feature which we rely on here so we cannot immediately update to the new library. To fix this, we need to restore the refresh_events feature in cert_handler or find a new pattern to use here.
Enhancement Proposal
15 includes a local fix to the cert_handler library to fix an issue with the hashing of cert input config
