Code Issues Proposed changes

make the sphinxpolicygen extension handle multiple input/output files

Browse Source 
Some projects have multiple policy files for different parts of their
API. Make the sample generator extension support this by letting the
policy_generator_config_file option be set to a list of tuples mapping
the config file to the output file base name, as we do in the sample
generator in oslo.config.

source directory (``app.srcdir``). If this option is not specified or is
invalid then the sample policy file generation will be skipped.
To handle cases where multiple files need to be generated, this
value can be a list of two-part tuples containing the path to the
configuration file and the base name for the output file (in this
case, ``sample_policy_basename`` should not be set).
``sample_policy_basename``
Base name of the output file. This name will be appended with a
``.policy.yaml.sample`` extension to generate the final output file and the
