"""It is simple CLI tool which allows to see and update mapping.json file
if needed. mapping.json contains all allowing OpenStack actions sorted by
service name. Usage example:
python tools/get_action_list.py nova
The result will be simple JSON containing action name as a key and method
path as a value. For updating mapping.json it is need to copy all keys and
values of the result to corresponding section of mapping.json:
...mapping.json...
"nova": {
<put it here>
},
...mapping.json...
Note: in case of Keystone service, correct OS_AUTH_URL v3 and the rest auth
info must be provided. It can be provided either via environment variables
or CLI arguments. See --help for details.
