cli: Add support for address book

[matevz]

Fixes #892

• adds addressbook command with subcommands add, rm, rename, list and show
• stores native address and optionally ethereum address, if the address is a valid ethereum address
• throws error, if withdrawing or transferring on consensus layer to a known account which is an ethereum account
• makes importing and printing ethereum keys and addresses consistent

Example:

$ oasis addressbook add myaddr
? Address (bech32 or hex-encoded): [Enter 2 empty lines to finish]oasis1qq3agel5x07pxz08ns3d2y7sjrr3xf9paquhhhzl

? Address (bech32 or hex-encoded): 
oasis1qq3agel5x07pxz08ns3d2y7sjrr3xf9paquhhhzl

$ oasis addressbook show myaddr
Name:             myaddr
Native address:   oasis1qq3agel5x07pxz08ns3d2y7sjrr3xf9paquhhhzl

$ oasis addressbook add myethaddr
? Address (bech32 or hex-encoded): [Enter 2 empty lines to finish]0x90adE3B7065fa715c7a150313877dF1d33e777D5

? Address (bech32 or hex-encoded): 
0x90adE3B7065fa715c7a150313877dF1d33e777D5

$ oasis addressbook show myethaddr
Name:             myethaddr
Ethereum address: 0x90adE3B7065fa715c7a150313877dF1d33e777D5
Native address:   oasis1qpupfu7e2n6pkezeaw0yhj8mcem8anj64ytrayne

$ oasis addressbook list
LABEL                 ADDRESS

myethaddr             0x90adE3B7065fa715c7a150313877dF1d33e777D5

Hm, I don't think that conflating this with the usual wallet accounts is a good idea. I would add a new configuration section called address book which is explicitly made just for storing addresses and then support this as an additional address resolution source.

Almost there, left some minor comments and then it should be good to go!
