ServiceNow Command Line Interface (snow-cli)

This is (at the moment) a sample implementation of a CLI tool targeted at simplifying programatic access for integration.

Currently using only user/password access, but the library this is based on, pysnow, supports tokens, which will be implemented at some stage here, along with access to request credentials stored in Hashicorp Vault.

Example usage

Create a snow.yml config file in the same directoy as the snow.py (see snow.yml.example).
