Merge branch 'master' into feature/probe_ip_lookup
* master:
Change None to correct YAML "Null" syntax in ooniprobe.conf.sample.
Support CPython with patch from lunar https://trac.torproject.org/projects/tor/ticket/8507
Add the 'reports' group to the sample config file.
Change ooni.director.start() to set config.reports.pcap option.
Move config processing options to new function config.processConfigFile().
Rewrite config.generatePcapFilename().
