0.37.0

Please note some important changes with this release:

• The sysconfig DOCKER_OPTS improvement in #250 can potentially change the behavior of that environment variable as it now allows shell interpolation of any embedded variables. This should not affect most environments. If your DOCKER_OPTS does contains any expected $, please escape via \$ for previous behavior or be sure it will behave as expected before upgrading.
• The daemon restart option (which is deprecated) has been defaulted to nil instead of false when node['docker']['container_init_type'] is set to prevent issues with container restart policies. If you're dependent on the daemon option, please be sure to update your node['docker']['restart'] appropriately.
• This release also defaults systemd docker host to fd:// to match upstream, enabling socket activation properly. Adjust node['docker']['host'] if necessary.
