Port Playbooks to Ansible 2.0

[oguya]

There are couple of warnings that I've received when running these playbooks using ansible 2.0.

• Use synchronize module rather than rsync

  TASK [solr : Copy solr.xml config. files] **************************************
  changed: [localhost]
  [WARNING]: Consider using synchronize module rather than running rsync
  

• Remove bare variables—e.g. solr_cores—use full variable syntax instead—e.g. '{{solr_cores}}'

  TASK [solr : Create Solr core data dir] ****************************************
  [DEPRECATION WARNING]: Using bare variables is deprecated. Update your playbooks
  so that the environment value uses the full variable syntax ('{{solr_cores}}').
  This feature will be removed in a future release. Deprecation warnings can be 
  disabled by setting deprecation_warnings=False in ansible.cfg.
  changed: [localhost] => (item=ckan_default)

Apart from bare variables & sudo/sudo_user, I don't see any other changes to make.
