add backlinks to report docs + consistentify!

    * I am a dummy and it took me awhile to figure out that the standard
    query parameters are listed in reports.md. This patch adds a
    "Request" section to each report file that links backs to the
    sandard request parameters in reports.md.  It also adds links back
    to the standard response parameters.

This PR supercedes my previous PR, so I shall close it.

Thank you!
