Feature/bindle secure config

@denis-yuen You can take a look at "Configuration Profiles" section  in the README which describes the usage of config files. This feature has moved bindle configs to ~/.bindle/ and also checks and updates them if the files at ~/.bindle/ are outdated. Also, if ~/.bindle/ doesn't exist, then it creates the folder with all the config files. I have successfully tested a 2-node cluster on OICR openstack with this code.
