Jessie support removed as jessie-backports was shut down. Also removed support for python2 since modern systems either have python3, or can install python3.

Don't delete staple files for invalid certificates, instead zero the file so HAProxy will still serve staples once the certificates are valid again. And fix some PEP8 and pylint issues.

Fix broken exception handling in python 2, version script still contains some instances but it doesn't run in production.

Finalise the parsing of HAProxy config files feature and a whole bunch of cleanup and code readability issues.

Replace ocspd with stapled and OCSPD with Stapled and OCSP\* with Staple\*, move files from any ocsp(d) to staple(d) too.

Allow config files in /etc/ocspd/ocspd.conf, ~/.ocspd.conf and /home/chris/projects/ocspd/ocspd.conf, read them at startup, give CLI args precedence, add a config template, add a service template.

excepthandler now gets the argparser from configargparse, parses that to find logdir. __main__.py still needs to be changed though

First step to back porting to python2.7, fix colourlog for python3 (also fix a few unrelated PEP8 issues)

re-call sendall in the OCSPAdder's send function and catch a second BrokenPipeError in the ocsp_handle_except function
