dongsam e30b125725 consensus: double-sign risk reduction (ADR-51) (#5147 )

Implementation spec of Double Signing Risk Reduction [ADR-51](https://github.com/tendermint/tendermint/blob/master/docs/architecture/adr-051-double-signing-risk-reduction.md) by B-Harvest
- Add `DoubleSignCheckHeight` config variable to ConsensusConfig for "How many blocks looks back to check existence of the node's consensus votes when before joining consensus"
- Add `consensus.double_sign_check_height` to `config.toml` and `tendermint node` as flag for set `DoubleSignCheckHeight`
- Set default `consensus.double_sign_check_height` to `0`  ( it could be adjustable in this PR, disable when 0  )
