* This is a fix for a potential security issue; the old code had edge
cases with unexpected behavior.
* LEMUR_RESTRICTED_DOMAINS is no more, instead LEMUR_WHITELISTED_DOMAINS
is a list of *allowed* domain name patterns. Per discussion in PR #600
* Domain restrictions are now checked everywhere: in domain name-like
CN (common name) values and SAN DNSNames, including raw CSR requests.
* Common name values that contain a space are exempt, since they cannot
be valid domain names.
Mostly typos, grammar errors and inconsistent indentation in code
examples.
Some errors detected using Topy (https://github.com/intgr/topy), all
changes verified by hand.
* Enabling the specification of a default authority, if no default is found then the first available authority is selected
* PEP8
* Skipping tests relying on keytool
* Implement CFSSL issuer plugin
Implement a Lemur plugin for generating certificates from the open
source certificate authority CFSSL
(https://github.com/cloudflare/cfssl). The plugin interacts with CFSSL
through the CFSSL REST API. The CFSSL configuration is defined in the
lemur.conf.py property file using property names prefixed with "CFSSL_".
* Update documentation to include CFSSL plugin
