Why not set a default storagePath?

So I guess there are at least two issues with that:

• What to do if the directory already exists? Should one of --resume or --overwrite be the default as well (probably not --overwrite?) or do we just error out here in that case
• Workers don't use a storagePath:

  fuzzilli/Cloud/GCE/start.sh

  Line 205 in f31ba8e

  --container-arg="sysctl -w 'kernel.core_pattern=|/bin/false' && ./Fuzzilli --logLevel=warning --jobs=$NUM_WORKERS_PER_MACHINE --networkWorker=$master_ip:1337 $FUZZILLI_ARGS $BINARY" \

That said, maybe we could add an explicit --no-storage flag or something like that, or we could turn this line

fuzzilli/Sources/FuzzilliCli/main.swift

Line 462 in f31ba8e

logger.warning("No filesystem storage configured, found crashes will be discarded!")

into a fatal error, so I'm open to suggestions here.
