cons3rt cli installed non-globally still requires global configuration

[codrcodz]

Issue

When installing pycons2rtapi in a non-global manner (i.e. via virtualenv or with --user), the user is still required to have sudo access so that the client can bootstrap the global config directory in /etc/pycons3rt/conf, even though it is not using it to store its configuration file.

Steps to reproduce

Use this role and/or follow manual steps similar to these, omitting the step where /etc/pycons3rt/conf is created manually:

• https://github.com/codrcodz/hmc/blob/master/roles/ansible-role-cons3rt-cli/tasks/main.yml

Once installed, run any cons3rt command (i.e. cons3rt --help) and you will notice that a permission denied error is thrown because the client is unable to automatically create the directory in /etc/ without passing sudo. Passing sudo makes the config files installed in the virtualenv or local user directory owned by root making them unusable without chowning them or calling the client with sudo each time.

Recommended fix

Have the client create the global configuration directory conditionally, instead of always.
