Research removing docker dependency in mkchain

[brandisimus]

Currently using docker to generate keys (tezos docker image) and creating a genesis block hash (in flextessa). This is an akward and unnecessary complication on the pipeline and ideally would be replaced with a simpler solution if possible. This ticket requires research wrt this possibility.

WIP creating block hash without flextesa:

from base58 import b58encode_check
from hashlib import blake2s
​
seed = str.encode(
    "".join(random.choice(string.ascii_uppercase + string.digits) for _ in range(16))
)
​
print(seed)
blake = blake2s(seed)
print(blake.digest_size)
# Prepend letter B
blake = b"\x01\x34" + blake.digest()
print(blake)
print(b58encode_check(blake))

The above is based on me talking to Seb and this link https://tezos.stackexchange.com/a/1213/3189. The tezos node accepts the output. Still requires more testing

Seb mentioned that it may be possible to use ssh gey gen which is (almost?) available everywhere to generate keys.

This issue is related to PR #154. We likely could still remove docker and generate random genesis blocks with blake2b and keys via python lib nacl. This is currently implemented in config-generator thanks to Roland
