Subject: [PATCH] X509 fixes (#111)
* Return proper content type for the x509 certificate
* Remove parenthesis
* Remove extra-variables during the import
* Comment fix
* Remove double returns
* Change log level from trace to debug
* Remove 'pass' and add logging instead
* Remove unnecessary wrapping
Remove wrapping
* PEP 8: line too long
PEP8: line too long
* PEP8: Redefine RSAError variable in except clause
* Do not return None if name was not found
* Do not return None if no matched minions found
* Fix unit tests
Fix for log checking in x509 test
We are logging in debug and not in trace mode here.
