The configurable values are as follows:
* `TimeoutPropose`
* `TimeoutPropose`
* How long the consensus algorithm waits for a proposal block before issuing a prevote.
* If no prevote arrives by `TimeoutPropose`, then the consensus algorithm will issue a nil prevote.
* `TimeoutProposeDelta`
* `TimeoutProposeDelta`
* How much the `TimeoutPropose` grows each round.
* `TimeoutPrevote`
* How long the consensus algorithm waits after receiving +2/3 prevotes before
issuing a precommit.
* `TimeoutPrevoteDelta`
* `TimeoutPrevote`
* How long the consensus algorithm waits after receiving +2/3 prevotes with
no quorum for a value before issuing a precommit for nil.
(See the [arXiv paper][arxiv-paper], Algorithm 1, Line 34)
* `TimeoutPrevoteDelta`
* How much the `TimeoutPrevote` increases with each round.
* `TimeoutPrecommit`
* How long the consensus algorithm waits after receiving +2/3 precommits with
no quorum before entering the next round.
* `TimeoutPrecommitDelta`
* `TimeoutPrecommit`
* How long the consensus algorithm waits after receiving +2/3 precommits that
do not have a quorum for a value before entering the next round.

* `TimeoutPrecommitDelta`
* How much the `TimeoutPrecommit` increases with each round.
* `TimeoutCommit`
* `TimeoutCommit`
* How long the consensus algorithm waits after committing a block but before starting the new height.
* This gives a validator a chance to receive slow precommits.
* `SkipTimeoutCommit`
