Reworked the include and update port sections

Jonas Karlsson requested to merge rework into main

Updated the format so that the challanges can be built and run standalone without any changes:

  • Now every challenge need to specify a port-id that maps to the port published in the ports section (in services), removs the need to invalid port numbers (eg. ${FLAG}:80)
  • Only ports that are specified in a challenge will be dynamic dynamic
  • Replaced ${ with crl{DYNAMIC} as magic word for identififying flags that should be autogenerated, will make the flags visable as crl{DYNAMIC} when running standalone (instead of empty string)

Added flag-format specifier to blueprint: If one adds a sectyion like this to the blueprint :

x-ctfd:
  flag-format: 'FLAG{{{FLAG}}}'

The resulting flag will be : FLAG{auto_generated_flag_here} The syntax of the flag format follows the python .format syntax (only allowed keyword is {FLAG})
