Do not show passwords in Ansible output

This role prints passwords in Ansible outputs (e.g. when creating
users, etc.). This is a problem because passwords must never appear
in plaintext under any circunstances.

This commit attempts to fix the problem described above. The option
"no_log: true" has been added to tasks which may print passwords
during Ansible execution.
