zetaclient zetatool : command to fetch ballot index from inbound hash and chain id

[kingpinXD]

We have an initial implementation of the command under zetaclient
https://github.com/zeta-chain/zeta-node/blob/47c9444bbd115176a2736f31be8cb7d23b0059e7/cmd/zetaclientd/inbound.go#L28-L190

This should be improved to

• Work with solana inbound
• Moved to the zetatool directory
• The command should standalone, and contain all the necessary configuration. It should not require a zetaclient config to function.

Expected Outcome

• A user should be able to use a cli command such as
  get-ballot [inbound hash] [chain-id] , which returns a ballot identifier .
