Standalone benchmark [wip]

[Lazar955]

Currently, the benchmark tool spins up various Docker containers and routines that emulate our side programs (vigilante, finality provider, btc-staker, covenant) and runs in an e2e flow.

The DevOps team requires that the benchmark tool can connect to an existing babylon node and have the ability to create a lot of delegations.
The btc-staker part of the benchmark would require significant change.

The new command should enable the user to specify:

• Number of Stakers
• Total number of delegations
• RPC endpoint of the Babylon node
• BTC node

We need to ensure that the Staker has funds both for bbn and btc, as it sends transactions to both.

Staker should also be able to do baby delegations not only BTC.
