Switch to Fedora-x86_64-20-20140618-sda

The heat-slow job using the Fedora-20 image as L2 guest, the
currently used version is affected by the heartbleed issue and
the Mb-Bios bug issue observed with emulation.

This version of the  Fedora cloud image uses the no_timer_check
kernel parameter, which solves the MP-Bios Bug issue.

The Image tested with ~3000 heat-slow job, without any issue.

Use None instead of mutables in method params defaults

Mutables in the method params defaults might cause errors and
that's why it's anti-pattern in most of the cases and should be
removed.
