Restructure API

[aharriscybr]

Current API will not work with hashi provider

[aharriscybr]

CyberArk API needs a namespace refactor and library refactor:

• Cannot use cyberark package name in API AND in Hashi Plugin
• Collapse separate calls to one main library
  • maybe?
• Refactor client to capture new client for authentication and onboarding tasks

Refactored for hashi overlay implementation Converted types to strings broke type structs from types

• Update readme
