Cap ansible < 2.0 for ansible-lint compatibility
Cap ansible < 2.0 for ansible-lint compatibility

Currently ansible-lint does not support Ansible 2.0, which was
released yesterday afternoon.

This is being worked on in:
https://github.com/willthames/ansible-lint/issues/75

This patch caps Ansible to < 2.0 to allow the gate checks to
succeed. This patch can be reverted once ansible-lint supports
Ansible 2.0 and above.
