Remove support for cookieSet

Type of issue

cleanup

Description

In older versions of Prebid Server, the cookieSet feature was used to improve uids cookie rate. This feature is no longer used by any of the major Prebid Server host companies.

I propose removing the feature and cleaning up the documentation.

@mkendall07 @bretg Does this need further discussion or do we need a PR for this?
