prathamesh0 3f79c2b811 [WIP] Handle restarts in fixturenet-eth stack (#324)
* Use mounted volumes for data in geth nodes

* Use mounted volumes for data in lighthouse nodes

* Avoid resetting genesis time in a lighthouse node on restart

* Mount parent datadir for lighthouse nodes

* Trap signals on shutdown and clean up in lighthouse nodes

* Allow stalled sync in lighthouse beacon nodes

* Gracefully shutdown geth nodes

* Add clean up instructions

* Gracefully shutdown lighthouse boot node
