feat: improve makejinja functions and cloudflared deployment

[onedr0p]

With cloudflared use TUNNEL_TOKEN instead of mounting in the creds.json and passing the tunnel id as an arg.

TUNNEL_TOKEN must be base64encoded, e.g.

apiVersion: v1
kind: Secret
metadata:
    name: cloudflared-secret
stringData:
    TUNNEL_TOKEN: |
        eyJhIjoiZmFrZSIsInQiOiJmYWtlIiwicyI6ImZha2UifQ==

echo "eyJhIjoiZmFrZSIsInQiOiJmYWtlIiwicyI6ImZha2UifQ==" | base64 -d
{"a":"fake","t":"fake","s":"fake"}
