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.
They test both module and service which is a bit wrong, but separating these
tests will lead to some duplication, so it's OK for now to have them in the
higher-order package (service imports module).
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.
Notice that it makes the node accept Extensible payloads with any category
which is the same way C# node works. We're trusting Extensible senders,
improper payloads are harmless until they DoS the network, but we have some
protections against that too (and spamming with proper category doesn't differ
a lot).
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.

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.
