CTF crl integration flawed

There are several issues in the crl/ctfd integration

• Challenges are never removed
• Challenges is only updated at creation time
• In jeopardy style (published ports) all non statict connection-infos will be wrong
• If two challenges have the same name (=hostname if not defined) only 1 will be created/used even if they are defined in different blueprints.
  • This is problematic as it does not scale to keep track of all challenge-names in all blueprints.

Possible solutions:

1. We create unique challenges per world/user or blueprint (name/category/blueprint)
   • If we use a separate ctfd per world/user
     • Solves all the above
     • Maybe somewhat messy and requires automatic ctfd creation
   • A in between is to split per blueprint but then connection-info will still be wrong
   • If we do split the challenges per world (with world=username) we might run into privacy issues as other will see what other users have solved, issue or not ?
2. Connection-info is the major problem as we create unique ports per world/user but challenges are shared.
