Bump shellcheck to v0.10.0 (#216)

- Bump shellcheck to v0.10.0
- explicitly disable SC2317 since it's reporting
  many false positives for us (we have helper functions
  that are only indirectly called in subshells for
  parallel executions but shellcheck is currently not able
  to follow them and so it's reporting the commands
  in the helper functions as unreachable)
