Enable yamllint for ansible playbook .yml files

Enabling yamllint for the ansible playbook .yml files. Modified
the default yamllint configuration to ignore some minor issues
so yamllint will pass. Made some very basic formatting changes
to the playbook files to address basic warnings/errors and
get the maximum line length to 125 characters.
