Upgradability

[MaksymZavershynskyi]

Nearcore node should support being upgraded, this includes:

• Discussion on how we want upgradability to work:
  • Do we want the node to be upgraded automatically or manually by the user?
  • Who determines the output?
  • In what cases the upgrade needs to be backward compatible?
  • etc.
• Design and implementation of config upgradability;
• Design and implementation of binary upgradability.

Wanted to port last bullet point of this issue: #1951

• “Create incentive for nodes to upgrade efficiently/quickly

Good actors with bad node hygiene will damage the health of the network. We need to create incentives for upgrading quickly (this is not relevant if we choose automatic upgrades). Likewise we may need to punish people with out of date nodes.

Likewise we may need to punish people with out of date nodes.

Note: It's not relevant to the upgradability itself. It's related to the consensus algorithm.
If majority of nodes are following the protocol it means they will be updated. It turns out that the remaining nodes will not follow protocol and fork - and thus will be punished by the consensus.

Protocol upgradability is implemented. See https://nomicon.io/ChainSpec/Upgradability.html for details
