daniel 41daf4d0d5 REST: Deprecate using "post" as the parameter source
Note that "post" parameters remain accessible through
getValidatedParams(), while "body" parameters have to be
accessed though getValidatedBody().

This adds a number of tests that ensure that this remains to be the case,
while deprecation warnings are triggered when appropriate.

Code search to check that this is unused in prod: https://codesearch.wmcloud.org/things/?q=SOURCE+*%3D%3E+*%27post%27&files=&excludeFiles=&repos=
