The existing `version` field should be called `software_version` but we will leave it for now to reduce the number of breaking changes.
Upon handshake, the node will check that the returned version string matches `TMCoreSemVer` else it will return an error.
We also need to be able to update versions throughout the life of a blockchain. The natural place to do this is EndBlock.

### RPCVersion
The goal with the RPC, is to have something that can be robust to the developments of Tendermint over time yet
be a reliable interface for the entire lifespan of a blockchain
There are two relatively distinct ways that the RPC can be modified and thus require a new version:
The first is that the block protocol changes. This means that the response and perhaps even the request
is modified to support the new data structures. The second are the endpoints themselves.
RPCVersion does not need to be included outside of the RPC. The `/status` endpoint will hold the version number so that external clients can simply query `/status` as part of their handshake with the rpc server.
