feat(ctfd): Manage CTFd-Helm deployment in manage-multijuicer.sh

[netr0m]

In order to manage the CTFd deployment, we should incorporate it into our preexisting deployment script so that all resources are created/destroyed upon deployment/taking it down.

1. Deploy & Destroy:
   • Spin-up: deploy_ctfd() (see here for an example)
   • Tear-down: destroy_ctfd() (see here for an example)
2. Configure INGRESS & TLS:
   • TLS: Add a host (see here for an example)
   • Ingress: Add a rule (see here for an example)
3. Configure DNS:
   • Add record (see here for an example)
   • Remove record (see here for an example)
