Stop the REA harvester at the same time as zef

This will make the sunsetting of p6c and cpan clearer and more
definite.  It also wouldn't necessitate REA offswitching by default.

Anybody who would still like to use p6c / cpan as an ecosystem, is
welcome to take the REA harvester code and set up their own ecosystem
which can then be activated in zef by those people who would like to
do that.

 Any module authors still not having moved their modules to the zef ecosystem by July 1st 2022, should be informed with a i**single** issue that lists the modules in question.  This could be an issue in the problem solving repo, but another repo would work as well.  The module authors should also be able to indicate they no longer wish to support a module themselves: in that case, a move to the raku-community-modules repo should be considered.

 - Offer to move any remaining modules to raku-community-modules
 Any authors still having modules in the p6c and CPAN ecosystems, should be offered help in moving their modules to zef and/or the raku-community-modules repo (which would then be followed by a move to the zef ecosystem).

 - Security updates on remaining modules
 Any module remaining in the p6c and CPAN ecosystem, should be forked in the raku-community-modules repo and re-released with a version bump if a security update to these, clearly abandoned modules, is necessary.
