Catch renew errors & Delete certs

[prionkor]

We have a white labeled part in our app where we provide le ssl for our users. However in few cases users changes their domain or no longer using our app in those cases attempt to renew domain fails. Here is a related log:

Processing login.example.com
 + Checking domain name(s) of existing cert... unchanged.
 + Checking expire date of existing cert...
 + Valid till Apr  1 12:40:01 2019 GMT (Less than 30 days). Renewing!
 + Signing domains...

 + Generating signing request...

 + 1 pending challenge(s)
 + Deploying challenge tokens...
 + Responding to challenge for login.example.com authorization...
Invalid challenge: DOMAIN=login.example.com RESPONSE={
  "type": "http-01",
  "status": "invalid",
  "error": {
    "type": "urn:acme:error:connection",
    "detail": "dns :: DNS problem: NXDOMAIN looking up A for login.example.com",
    "status": 400
  },
  "uri": "https://acme-v01.api.letsencrypt.org/acme/challenge/-UWJLolllllllllllllllllll/14288788129",
  "token": "-GgMs_L_llllllllllllllloTb6fw1CKKZoic"
}

Is it possible to perhaps cache these errors and remove these domains certs from the directory so the auto ssl doesn't attempt to renew them again?

Related to an issue I opened. A possible solution is here: #150 (comment)

@edeis53 Thank you, the solution provides catching the now allowed domain. Not expired or DNS errored domains

I think this should hopefully be resolved in v0.13.0 between the combination of #176 and #128. Sorry for the long delay in addressing this! So I'm going to close this, but let me know if there were still any outstanding issues with the behavior in the new release.
