cli: add serialize-transfer and execute-signed-tx commands

[joyqvq]

Add two cli command (serialize-transfer-sui at Step 1 and execute-signed-tx at Step 3). This is useful if the user just want to serialize the data with CLI and take the signing offline somewhere else (wallet of your choice, or tools in other languages). And come back with a signed transaction just to execute it.

This is useful for us to ensure serialization consistency btw ts-sdk and rust.

Step 1: Serialize the Data

target/debug/sui client serialize-transfer-sui --to 0x581a119a6576d3b502b5dc47c5de497b774e68ca --sui-coin-object-id 0x0599b794da39169f7c75d34eba06ae105fedc61b --gas-budget 1000

Step 2: Sign the data

This can be done elsewhere in your signing device of your choice, here uses the keytool command as a PoC.

target/debug/sui keytool sign --address 0x581a119a6576d3b502b5dc47c5de497b774e68ca --data VHJhbnNhY3Rpb25EYXRhOjoAA1gaEZpldtO1ArXcR8XeSXt3TmjKAFgaEZpldtO1ArXcR8XeSXt3TmjKBZm3lNo5Fp98ddNOugauEF/txhsCAAAAAAAAACC0knjIoZEdbQBQuqg3feG/GA0L2v9gLDfH2uX8iGf5SwEAAAAAAAAA6AMAAAAAAAA=

Step 3: Execute the tx with its data and signature that it committed to

target/debug/sui client execute-signed-tx --tx-data VHJhbnNhY3Rpb25EYXRhOjoAA1gaEZpldtO1ArXcR8XeSXt3TmjKAFgaEZpldtO1ArXcR8XeSXt3TmjKBZm3lNo5Fp98ddNOugauEF/txhsCAAAAAAAAACC0knjIoZEdbQBQuqg3feG/GA0L2v9gLDfH2uX8iGf5SwEAAAAAAAAA6AMAAAAAAAA= --scheme ed25519 --pubkey rJzjxQ+FCK9m8YDU8Dq1Yx931HkIArhcw33kUPL9P8c= --signature epIttAjg4OBOzVBQQuMflR9sJwh12XiBFwDV9gmiBxomKJ0YyjcbhLONdvA1xs2NXy8xdagwHR/uRVdI6z+LAg==

This LGTM! regarding maintenability, I was wondering if we had an integration test covering the CLI, in the style of https://docs.rs/assert_cli/latest/assert_cli/index.html

Indeed, I'm afraid of us breaking this tool inadvertently by changing the transaction format. assert_cli is really easy to use and would offer some protection against this I expect. I'd highly encourage adding a basic test of those 2 commands.
