SUMMARY

Change 'content_root' to 'collections_path' and make 'ansible_collections' implicit Fixes: #239

From CHANGELOG.rst

• WARNING: The config file items and cli options for specifying install paths have changed and may break existing configs and scripts.
• The config item content_root has been replaced with collections_path
• The config item global_content_root has been replaced with global_collections_path
• The new collections_path value no longer needs to end with ansible_collections
• The new global_collections_path value no longer needs to end with ansible_collections
• The new collections_path defaults to ~/.ansible/collections. Note that this replaces the previous content_root config item that defaulted to ~/.ansible/collections/ansible_collections
• The new global_collections_path defaults to /usr/share/ansible/collections. Note that this replaces the previous global_content_root config item that defaulted to /usr/share/ansible/collections/ansible_collections
• mazer install with default collections_path (~/.ansible/collections) will still install to ~/.ansible/collections/ansible_collections, but install will add the require trailing 'ansible_collections' automatically.
• mazer install --global with default global_collections_path (/usr/share/ansible/collections) will still install to usr/share/ansible/collections/ansible_collections, but mazer install --global will add the require trailing ansible_collections automatically.
