Title: Use heroku-api gem and process commands in parallel for each heorku app via fork child processes 

Remove dependency to 'heroku' gem.
Use 'heorku-api' gem to run commands.
Parallelize commands to be run on multiple heorku apps:
bundle exec rake company1:staging company2:development heroku:deploy
Will create 2 forked child processes each running against a different heroku app.
