Add sudo package for bootstrap-servers

sudo package is required when we use ubuntu base on centos to deploy.

The following tasks belong to the environment check after
installation of environment-related software packages.
So, move to the post-install module.

    Create kolla user
    Add public key to kolla user authorized keys
    Grant kolla user passwordless sudo
    Ensure node_config_directory directory exists for user kolla
    Ensure node_config_directory directory exists
