V2 Saturn 0 changes + node deposit and stake-rpl updates

[thomaspanf]

This PR includes changes from #681 and #694

In summary:

• Removed 16ETH options
• Removed some node status text that isn't needed in Saturn 0
• Updated messages and workflow for node deposit (Saturn 0 message, smoothing pool check, 8 eth deposit hardcoded, --a and --y flags still available)
• Removed stale node stake-rpl options now that node.per.minipool.stake.minimum == 0
• Replaced those options with 5,10, or 15% borrowed ETH as RPL as well as custom percentage inputs passed within the command or as a CLI flag.
