Library for Custom Action functions

Feature: Library to store custom functions to be used across different custom actions

Description: There could be a place for custom functions that could be used/imported into different actions. That way you don’t need to write same code multiple times. Secrets and dependencies could be set there per function also. So it would be easy to consume it in action. Just import and call it.

Use-case: We have coded same ManagementClient initialization with token cache handling code in different actions. For example I would do a token handling and fetchManagementAccessToken functions into this library and use them in different actions.
