Usage: bolt-inventory-pdb <input-file> [--output <output-file>] [--url <url>] [auth-options]

Populate the nodes in an inventory file based on PuppetDB queries.

The input file should be a Bolt inventory file, where each 'nodes' entry is
replaced with a 'query' entry to be executed against PuppetDB. The output will
be the input file, with the 'nodes' entry for each group populated with the
query results.
