content-rest mappings hide data rest endpoints for "PATCH" and "HEAD" methods

[bushaev]

ContentHandlerMapping#lookupHandlerMethod returns lookup method for mapping, unfortunately because ContentHandlerMapping#isHalOrJsonRequest ignores "PATCH" and "HEAD" methods, rest endpoints created by Spring Data Rest get hidden and therefor it's impossible to perform "PATCH" update on "content entity" and "PUT" update with content-type header application/json erases file. It would be great if the support for these methods was added as well!

Hi @bushaev, this sounds like a bug. Spring Content shouldn't be trampling on Spring Data endpoints. Especially if we dont yet use them ourselves. As an aside I have never been happy with that isHalOrJsonRequest as it precludes json from being content which in some use cases it might be. Anyways, we'll fix this.
