Updated the local network simulation scripts to use the REST interface
for connecting the validator client to the beacon node. Otherwise, the
current scripts produce errors.
* Concentrate all sensitive writeFile/createPath calls in one place.
Fix eth2_network_simulation for Windows.
* Remove artifacts.
* fix import

- better logging & retrying requests on the VC side if the BN fails for some reason
- VC now fetches the attestation duties 1 epoch in advance - in the future it will tell the BN to subscribe to the appropriate attestation topics in advance based on that info
- a bunch of other code cleanup & fixes such as better naming for consoles when using multitail, etc.
reviewed in PR #1184 - proper review of the API & VC are pending
- each BN gets half of its previous validators as inProcess and the other half goes to the respective VC for that BN - using separate data dirs where the keys are copied
- also removed a few command line options which are no longer necessary
- block proposals originating from a VC are propagated from one BN to the rest properly
- other cleanup & moving code back to since it is no longer used elsewhere
