Rest: Remove 'case' parameter from rest apis

The current api allows for choosing which "case" response json keys are
written in. This has the options of camelCase or underscore. camelCase
is going to be deprecated from the query apis. However, with the case
api, it is not necessary to deprecate, as users who were using it in 2.x
can transition completely on 2.x before upgrading by simply using
the underscore option.

This change removes the 'case' option from rest apis.
