Add EigenLayer support

[Marketen]

In order to enable restaked validator with EigenLayer, we need to add some logic to oracle's "manualSubscription" handler.

• when subscribing manually, if TX sender != validator withdrawal credentials check if TX sender is the owner of an EigenPod.

  • If it is not, do not accept the subscription (same output as now)
  • If it is, Filter this EigenPod's ValidatorRestaked events:
    • If one event includes the validatorID we're trying to subscribe, let the subscription go on
    • If not a single ValidatorRestaked has the validatorID we're trying to subscribe, do not accept the subscription

• autosubscribing is not a problem, send reward to withdrawal address (eigenpod). EigenPod withdrawals are available & doable through eigenlayer UI
