feat: Prompt to select what to nuke and iOS simulator

[cszatmary]

• tb nuke now works with no flags and will prompt the user to select one or more things to remove.
  
• tb app ios run and tb app ios logs now prompt the user to select an iOS simulator. Previously it would try to pick a default but this had issues and was confusing for users.
  
• Nuking images, volumes, or networks now also stops and removes containers. Previously this would break if tb down was not run first since these resources cannot be removed when used by containers.
• Fixed some cases where using control-C to terminate the program would not have the correct exit code and would display the logfile path.
