Title: Document HARNESS_PERL_SWITCHES

I noticed it wasn't documented, but its mentioned all over various Perl documentation. In particular its how you make [Devel::Cover](https://metacpan.org/module/Devel::Cover) work with prove or `make test`.

It would be nice if there was a prove switch to control Perl switches.
