implement callbacks to show attributes if farm is enabled

[MustafaJafar]

Changelog Description

This PR implement callbacks to some plugins show attributes if farm is enabled.
I only tested it in Houdini.

Note

This PR is mainly made for sharing code and show a use case for ynput/ayon-core#994
It should be used along #49 and ynput/ayon-houdini#149
Here's what to expect when using the three PRs togther

Testing notes:

1. Launch Houdini via AYON
2. Create a cache instance (vdb, model, pointcache, ass, rsproxy)
3. Switch farm toggle in the publisher UI, click save, click refresh and watch the attributes appear and disappear.

Sorry for the duplicated comment.
I did a simple test with the callback but it seems that it does not apply the change as the changelog description depicts. Is it expected behavior?

This PR is wrong.
the callbacks should be implemented on the CollectJobInfo plugin. (this is a new plugin implemented in #49 )
