Cooldown in AbilityData?

Many abilities have some time requirements - e.g. cast-time and/or cooldown. Would it be possible to expose that information in the `AbilityData`?

In my particular case:

I am trying to learn the rate at which Protoss gateway units can be produced. Normal construction time in a gateway is available in:
`bot->Observation()->GetUnitTypeData()[sc2::UNIT_TYPEID::PROTOSS_ZEALOT].build_time`
but I cannot find a way to learn about the warpgate cooldown after warp-in. I would expect something in:
`bot->Observation()->GetAbilityData()[sc2::UNIT_ACTIONID::TRAINWARP_ZEALOT].???`

A `cooldown` field would solve my problem.

Or maybe I can learn that info somewhere else?
