Error requesting new cert

[ooduor]

Apparently due to existing csr and key files.

[anthony@archilles request-certificate]$ ./request-cert ca.modio.se install.webapp
Key file install.webapp.key is valid; using it
Certificate signing request file install.webapp.csr is valid; using it
Starting new HTTPS connection (1): ca.modio.se
/usr/lib/python3.5/site-packages/urllib3/connection.py:266: SubjectAltNameWarning: Certificate for ca.modio.se has no `subjectAltName`, falling back to check for a `commonName` for now. This feature is being removed by major browsers and deprecated by RFC 2818. (See https://github.com/shazow/urllib3/issues/497 for details.)

The error here is that we're just raising the HTTPError.

The HTTPError from the server is completely valid & correct, request-cert should just be a tad nicer about what it does, and preferrably helpfully suggest:
"Delete your csr and start over"
