this changes is required due to recent #654.
custom genesis and chain config parser are fixed
and the genesis fields are grouped into "genesis"
field, similar with chain config fields,
they are grouped in "config" field.
trying Jacek suggestion in #591, I added nat setting to
nimbus-eth1 hive shell script. visible difference after adding
this flag is the nat library not complaining about
"the gateway does not support nat-pmp" anymore.
but the slow startup time described in #591 is yet to be measured
again, although I already see improvement when executing
ethereum/consensus category in hive.
- Explain some of the prerequisites in more detail (Go version).
- Practical issues around Go version and Docker configuration to make it work.
- Make the first example be one that works with nimbus-eth1.
(Instead of giving an obscure error message that looks like the user's Docker
setup is broken).
- Rename to `README.md` per convention.
