Crossplane version 2 upgrade

[Eli1123]

Overall was able to get V2 Crossplane upgraded and documented with things that needed to change to make that work.

Crossplane Compositions are the main problem currently.

• I believe I got S3, and DynamoDB functioning since they deployed after my changes however have not done a through test outside of it deployed.
• I kept the docs and attempt I had so far trying to fix the RDS composition incase that is useful

README_Crossplane_V2_Upgrade.md has the overall changes and upgrade both for crossplane and the compositions.

• I also added a .md file under each composition detailing what I've done.

I believe once the compositions are upgraded there should not be any major issues for Crossplane V2.0.2 upgrade.

README_Crossplane_V2_Upgrade.md has the overall changes and upgrade both for crossplane and the compositions.

Each composition is working now, and I used the tests under appmod-blueprints/platform/crossplane/examples/Crossplane_V2_tests and they all deployed successfully.

• I added .md files for each composition explaining what I changed.
• Also added .md file for the tests

If you feed these .md docs to amazon q it can do the upgrade for you without much input needed on your end as its well with how I set it up after you follow the steps for upgrading argo cd first.
