feat: accept arguments on eigenlayer type deployment

[MegaRedHand]

Closes #35

This extends the "eigenlayer" deployment type to support simple addition of strategies, auto-registration of operators, and strategy deposits.

The added syntax looks like:

deployments:
  - type: EigenLayer
    ref: v0.4.2-mainnet-pepe
    # This creates a single strategy named MockETH, which uses a mock-token
    strategies: [MockETH]
    operators:
      # This registers the operator in EigenLayer
      - name: operator1
        keystore: operator1_ecdsa_keystore
        # This sets the initial deposit for the operator in each strategy
        strategies:
          # strategy_name: number_of_tokens
          MockETH: 100000000000000000
