Ansible 2.6 prep

[sparkertime]

Deploys generate a few deprecation warnings that will become breakages in 2.6 . If SWSheets deployments remain on ansible, these need to be fixed:

[DEPRECATION WARNING]: The sudo command line option has been deprecated in favor of the "become" command line
arguments. This feature will be removed in version 2.6. Deprecation warnings can be disabled by setting
deprecation_warnings=False in ansible.cfg.

[DEPRECATION WARNING]: Instead of sudo/sudo_user, use become/become_user and make sure become_method is 'sudo'
(default). This feature will be removed in version 2.6. Deprecation warnings can be disabled by setting
deprecation_warnings=False in ansible.cfg.
