[keycloak-dev] Token validator endpoint (for humans)

I added an example token validator endpoint that I needed for some demonstration purposes. Question would this be useful to add directly to Keycloak? It provides a simple form where you can paste in the base64 token. It will then output the header, claims and whether or not the token is valid. It uses realm keys to verify the signature so you don't have to paste that in manually (like you do on jwt.io). For those to lazy to try it out I've attached a screenshot.
