Similar to how a license format [1] has been documented for bug 17682, we
should document the license request format.

For Clear Key, the message attribute of the needkey event is currently defined
as "a container-specific value extracted from the initData parameter of
createSession()."

Instead of defining a format for each container and requiring
applications/servers to support different formats for each container, we should
define a license request format. Defining a JSON-based format would be
consistent with the license format [1].

This also has the advantage of not passing a binary blob to the application as
would happen in the CENC case (bug 24027).
