Add missing exports in 'Ganeti.Types'
Add missing exports in 'Ganeti.Types' which are necessary for 'Ganeti.HsConstants'. These exports concern the '*ToRaw' functions which convert a Haskell type into JSON. These functions are needed by the constants which we want to generate from Haskell to Python based on Haskell types. Signed-off-by: Jose A.
