Document rule exclusion pkg to plugin migration from CRS3 to CRS4 in separate blog post

[dune73]

No need to rush this before the CRS4 release. But it's something to accompany the documentation.

@dune73 Do we want to do this in June? Or is there a timeline?

[dune73]

That would be an alternative to the idea to describe how to create your own plugin. And actually quite a good alternative. What do you think?

[dune73]

Ping @fzipi.

[fzipi]

Yes, makes sense. How to create your own plugin, and then mentioning that this is how we migrated things. 👍

[dune73]

OK. Consider this done!

[fzipi]

Do you want to keep this issue here or transfer to the webpage repo?

[dune73]

I'm all for migration to webpage.

As documented above I had planned to write this for the WAF month media campaign by OWASP's outreach coordinator Jason. Then he left and I did not write this.
