[#1711] adm: Implement local client's methods
Implement methods that `actor.Actor` requires: 1. `InvokeFunction` -- wrapper over `InvokeScript` 2. `GetVersion` returns default struct 3. `CalculateNetworkFee` copied and simplified from Neo-go server side. Signed-off-by: Pavel Karpy <carpawell@nspcc.ru>
