Plugin hook update

[bjeffries]

Description

This pull request addresses issues #3078 and #3079.

Currently there is a bug identified in #3078 that prevents the existing builder plugin from hooking the executor outside of the planning service. This is addressed by adding a similar check in the operations api manager.

Looking at the bigger picture, the executor hook check was specialized just for the builder plugin. The change below will parse through any hook that is added to the executor hook data structure allowing for other plugins to easily leverage this capability.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• This change requires a documentation update

How Has This Been Tested?

I have tested these changes on Caldera v5 with a plugin that leverages this hooking method to edit ability files before they are staged for an agent.
