Initialise services dependant on roles designation based on N+1
block so that Genesis roles extension work properly. There's not
much sence to fetch node roles information for the latest persisted
block because Designation contract itself makes designated nodes
responsible since the next subsequent block.
A part of #3228.

It requires explicit signers, and we have a problem with the old code:

We were using _very_ old version, so there is a number of changes, including:
* fix for unlimited reads
* UTF-8 check for HTTP requests
Signed-off-by: Roman Khimov <roman@nspcc.ru>
Everywhere including examples, external interop APIs, bindings generators
code and in other valuable places. A couple of `interface{}` usages are
intentionally left in the CHANGELOG.md, documentation and tests.
And include some node-specific configurations there with backwards
compatibility. Note that in the future we'll remove Ledger's
fields from the ProtocolConfiguration and it'll be possible to access them in
Blockchain directly (not via .Ledger).
The other option tried was using two configuration types separately, but that
incurs more changes to the codebase, single structure that behaves almost like
the old one is better for backwards compatibility.
Fixes#2676.
See neo-project/neo#2390. Can't see it there? No wonder, that's why we have
this bug for a year and a half. Not critical, we don't care about versions,
but _very_ annoying.
Which allows to enable/disable the service, change nodes, keys and other
settings. Unfortunately, atomic.Value doesn't allow Store(nil), so we have to
store a pointer there that can point to nil interface.
It doesn't add anything useful to regular Go types and actually native types
are always better to use in the Client. Especially given that this type is
not used by any code outside of the Client itself.
1. Move redirections check to the tcp level. Manually resolve request address
and create connection for the first suitable resolved address.
2. Remove URIValidator. Redirections checks are set in the custom http client,
so the user should take care of validation by himself when customizing the
client.
Update includes:
1. New simple client mode that parses erroneous status codes as `error` and
returns them from the calls of the client methods.
2. `Client` is struct now, not an interface.

Replace `neofs-api-go` module with `neofs-sdk-go`. Adapt to NeoFS
response statuses in the implementation of NeoFS oracle.

Problem: transactions with wrong hashes are accepted to the chain if
consensus nodes are designated as Oracle nodes. The result is wrong
MerkleRoot for the accepted block. Consensus nodes got such blocks
right from the dbft and store them without errors, but if
non-consensus nodes are present in the network, they just can't accept
these "bad" blocks:
```

```
This problem happens because of transaction hash caching. We can't set
transaction hash if transaction construction wasn't yet completed.
