Adding HolmesGPT plugin

[pavangudiwada]

This PR adds support for HolmesGPT an Open source DevOps assistant that helps with investigating issues in a cluster.

There are two modes, to customize the investigation.

If I'm not mistaken the custom-holmesgpt action leaves the temp-ask.txt file laying around. Not sure where this file would be placed (current directory?) but it should be cleaned up. In my humble opinion the name temp-ask.txt is also too generic.

Maybe even better: Create a temporary file using mktemp:

$QUESTION_FILE=$(mktemp)
${EDITOR:-nano} $QUESTION_FILE

@KevinGimbel You are absolutely right! I updated the custom-holmesgpt plugin. I'm not manually removing it because it's will be in the /tmp directory. Let me know if this works.

Looks better to me! Thanks 👍
