Having the repos directory in the docker directory causes it to be
sent to the docker daemon every time, which is a complete waste.
Best solution was to move the repos dir out of dockers
Fixed git clean to only be in build_rpms for centos path
Added tests for all distros
Added some options like GPG cache, and auto remove
Fixed rpm expect script to work always
Enabled gpg check for centos repos
Fixed golang build bug for CentOS 5
