Merge #15459: doc: add how to calculate blockchain and chainstate size variables to release process
eb4c43e49f625895670866b89bb56ca641c4eeb7 doc: documents how to calculate m_assumed_blockchain_size and m_assumed_chain_state_size on the release process. (marcoagner)
Pull request description:
Regarding [this](https://github.com/bitcoin/bitcoin/pull/15183#issuecomment-463133734) on https://github.com/bitcoin/bitcoin/pull/15183.
Added an "Additional information" section for this which seems reasonable to me but may not be the best place for this. Also, let me know if anything else should be documented here (like more details).
