Remove Unused Cookbook Metadata

There are a set of metadata fields that have never been really supported by Chef, and so we should remove them.


As a community advocate,
I want to ensure that cookbook maintainers focus on the things that
so that they can write better cookbooks.

As a chef developer,
I like removing code,
so that there are fewer bugs.


Mark as deprecated and subsequently remove the recommends, suggests, conflicts, replaces and grouping metadata fields.

Downstream Impact

Chef Server should be updated to not serve this metadata, docs need to be updated. Also, generators such as chef generate, berks cookbook need to be updated to ensure they do not create metadata files with those fields.
