Change help message for --batch

The help message previously said that `--batch` is strongly discouraged, but in fact it's only discouraged when using bazel interactively.  Since the tradeoffs of `--batch` are fully explained in the online docs, this commit changes the help message to explain what the option does without getting into the tradeoffs.

Fixes #3051

Closes #3118.
