Use 'pip freeze' output to detect changes with requirement specified

Browse source 
If the requirements contains a repos url it will always report 'Successfully
installed'; there is no difference in the output to tell apart if
anything new was pulled. Use freeze to detect if the environment changed
in any way.

Should fix ansible/ansible#1705
