Add node type information in Status message to let its peers know whether it is an Archive, Full, or Light node.
Currently, there is no way for a Conflux node to let its peers know what type it is, in the sense of Archive, Full, or Light. This CIP fix this issue by adding field of node type in Status message.
Conflux nodes need a way to convey what types they are to their peers, so that nodes can maintain the node type information of their peers and can decide how to choose peers to connect or send messages accordingly. For example, when light nodes want to retrieve old-era receipts or full nodes are in catch-up phase, they might need to query an archive node.

The proposed fix is protocol-breaking since it involves message format changing. It should use protocol versioning mechanism to implement, but at current stage in phase 2 mainnet, I prefer a direct in-place update in current message version.
TBD
See conflux-rust pull request #1701.
There is no obvious way to verify whether a node tells the truth about its type. But this would not introduce serious security issue. The node which uses this information of its peers will eventually observe the inconsistency between their behaviors and claims, and can demote their reputations accordingly.
