"""
This is the library of utility functions and classes for managing DECORT cloud platform.
These classes are made aware of Ansible module architecture and designed to be called from the main code of an Ansible
module to fulfill cloud resource management tasks.
Methods defined in this file should NOT implement complex logic like building execution plan for an
upper level Ansible module. However, they do implement necessary sanity checks and may abort upper level module
execution if some fatal error occurs. Being Ansible aware, they usually do so by calling AnsibleModule.fail_json(...)
method with properly configured arguments.
NOTE: this utility library requires DECORT platform version 3.4.0 or higher.
It is not compatible with older versions.
Requirements:
- python >= 3.8
- PyJWT Python module
- requests Python module
- netaddr Python module
- DECORT cloud platform version 3.8.6 or higher
