Simplifiable forEach() call

Reports forEach() calls that can be replaced with a more concise method or from which intermediate steps can be extracted.

Example:

List<String> findNStrings(List<String> list, int n) {
  List<String> other = new ArrayList<>();
  list.forEach(s -> {
    if(s.length() > n) other.add(s);
  });
  return other;
}

After the quick-fix is applied:

List<String> findNStrings(List<String> list, int n) {
  List<String> other = list.stream()
    .filter(s -> s.length() > n)
    .collect(Collectors.toList());
  return other;
}

This inspection only reports if the language level of the project or module is 8 or higher.
