Enable setting information_type via browser.

= Summary =
Support setting Specification.information_type via the browser

== Pre-implementation notes ==
Discussed with deryck

== LOC Rationale ==
Part of Private Projects

== Implementation details ==
This operation currently returns '', but will eventually return subscription information, as bugs do. Modifying a Specification's information_type but returning subscriber information is page-specific functionality and makes no particular sense in an API, so it is provided via the appservers, rather than the API.

The tests use create_initialized_view because this permits setting the HTTP_X_REQUESTED_WITH header, which allows for standard error handling.

== Tests ==
bin/test test_specification

== Demo and Q/A ==
Set the 'blueprints.information_type.enabled' feature flag to "on".

Change the information_type of a blueprint. It should succeed. Reload the page. The new information_type should be retained.
