Enables authorizations to be defined on GraphQL Types.
module Types
class ProjectType < BaseObject
authorize :read_project
end
end
If a field has authorizations defined on it, and the return type of the
field also has authorizations defined on it. then all of the combined
permissions in the authorizations will be checked and must pass.
Connection fields are checked by "digging" to find the type class of the
"node" field in the expected location of edges->node.

When working on files in `app/graphql` the code correctly gets
autoloaded.
However, the redefined `Types::BaseField` would never receive the
`.accepts_definition` call, causing all queries after a reload to
fail. Calling `.accepts_definition` on its superclass makes sure the
reloaded version also has the `authorize` definition specified.
Previously GraphQL field authorization happened like this:
class ProjectType
field :my_field, MyFieldType do
authorize :permission
end
end
This change allowed us to authorize like this instead:
class ProjectType
field :my_field, MyFieldType, authorize: :permission
end
A new initializer registers the `authorize` metadata keyword on GraphQL
Schema Objects and Fields, and we can collect this data within the
context of Instrumentation like this:
field.metadata[:authorize]
The previous functionality of authorize is still being used for
mutations, as the #authorize method here is called at during the code
that executes during the mutation, rather than when a field resolves.
