Bug 1380531 - Write initial CircleCI configuration for BMO

This is the first (working) iteration of a configuration that allows
CircleCI to build 'bmo' docker images that are runnable.

Some other changes were required for this:

1. The base image used in Dockerfile was changed from centos:6.7 to
   mozillabteam/bmo-base:slim.
   This is a new version of (github) mozilla-bteam/docker-bmo-base
   which is much smaller, and includes all the system RPMs and other
   bits that our bmo Dockerfile expects.
2. init.pl mistakenly had '--no-assets' which is not currently a checksetup.pl
   option.
3. 901-secure-mail-loop.t (which checks for an infinite loop) had
   to have its timeout increased because CircleCI sometimes is quite slow.
4. version.txt // __version__ now includes build information from CircleCI
   environmental variables
