Zahary Karadjov ee2448b221 Simple validator onboarding
On your very first connection to each testnet, you'll be asked to
become a validator. Please consult our private repo for a Goerli
Eth1 private key that you can use for deposits.

Other changes:

* Added a simple wrapper ./connect-to-testnet script calling the
  nims file in the correct environment. No extension was used to
  make the command the same on Unix and Windows.

* Bumped a number of modules with fixes from this week

* `make testnet0` and `make testnet1` will no longer delete your
  existing database. This is considered a more appropriate behavior
  for testing forward sync.

Zahary Karadjov 22591deced Safer testnet restarts; Working CLI queries for inspecting the genesis states
When the connect_to_testnet script is invoked it will first verify that
the genesis file of the testnet hasn't changed. If it has changed, any
previously created database associated with the testnet will be erased.

To facilitate this, the genesis file of each network is written to the
data folder of the beacon node. The beacon node will refuse to start if
it detects a discrepancy between the data folder and any state snapshot
specified on the command-line.

Since the testnet sharing spec requires us to use SSZ snapshots, the Json
support is now phased out. To help with the transition and to preserve the
functionality of the multinet scripts, the beacon node now supports a CLI
query command that can extract any data from the genesis state. This is
based on new developments in the SSZ navigators.

Multi-client testing requires more portable formats, and SSZ is
much better specified than our flavour of Json.

a network running with a different number of shards).
