🚀[Feature]: Add functionality to autorefresh managed IATs when expired

[MariusStorhaug]

Description

When running the GitHub module as a GitHub App via automation:
In function app for automation, we want to be able to have context retained and ready when a function is called towards a target.

When the IAT is detected and we have the context for the app, refresh the IAT.

Scenario:

• Automation is running in the context of a GitHub App (no IATs currently defined).
• Automation needs to run Delete-GitHubTeam -Name 'someTeam' -Organization 'someOrg'.
  • Delete-GitHubTeam requires, IAT, UAT or PAT, Team permission
• Module gets the context matching the request:
  • Type = IAT
  • Permissions contains 'Teams'
  • TargetType = 'organization'
  • Target = 'someOrg'
• If the IAT is found:
  • Module checks that the time now is greater than my TokenExpirationDate (subtract a var offset that can be stored in config)
  • Check if parent is available:
    • Type = 'App'
    • ClientID = $me.ClientID
• Recreate context for the IAT (or just refresh the token)
