No way to clear certificate request errors

[alexdlukens]

Bug Description

When we fail to provision a certificate for various reasons, we encounter an error: Skipping certificate request with persistent error

lego-operator/src/charm.py

Lines 186 to 191 in d735ae7

	if request_key in persistent_error_requests:
	logger.debug(
	"Skipping certificate request with persistent error: %s",
	certificate_request.certificate_signing_request.raw,
	)
	continue

After we fix the underlying issue, there is no way for us to tell LEGO to re-attempt requesting certificates. We need e.g. a juju action to clear-certificate-request-errors. Right now we must remove-relation and re-relate the application, requesting ALL certificates again

To Reproduce

N/A

Environment

PS7, lego rev274
