Consider using neofs-adm instead of fetching sidechain dump from contract release page

[alexvanin]

neofs-adm allows to deploy and configure smart contracts from genesis block. So we can provide compiled contracts and deploy environment step by step.

🟢 Pros: better integration with contract or deploy procedure changes
🔴 Cons: longer startup

Alternatively it can prepare chain dump once (nspcc-dev/neofs-node#722) and reuse it on every restart.

After internal discussion with @realloc:

• smart contracts should be compiled from source code in neofs-dev-env with expected neo-go version, we don't use archives from release pages,
• make initial implementation without chain dump preparation step,
• add optional chain dump preparation step later.
