Make `Client` to be the wrapper over raw protobuf client. Provide public
method to get the underlying raw client. Change implementations of all
methods with the new approach of the RPC execution.
Additional changes:
* key replaced from `New` argument to `WithDefaultPrivateKey` option;
* `GetSelfBalance` is removed as non-viable;
* `GetEACLWithSignature` is removed, `GetEACL` returns `EACLWithSignature`;
* `AttachSessionToken` / `AttachBearerToken` are removed as non-viable;
* redundant options are removed.

Make it easier to test API clients and mock specific methods.
Also add comments on exported methods.

Allow to reuse underlying connection for requests
with different key. If no key is specified the one
provided on client creation is used.

Object payload transferred in chunks. Size of the
chunks may be limited by transport protocols. To
split it we use `io.CopyBuffer` with pre-allocated
buffer size of one chunk. However this function may
ignore buffer if reader or writer implements
`WriteTo` or `ReadFrom` methods. Unfortunately
`bytes.Reader` implements `WriteTo` function.
To fix this we wrap reader so wrapper implements
only `io.Reader` interface.

There is a need to set dial timeout in SDK client that is used in case of
internal connection opening. Add DialTimeout option constructor to support
this feature.

According to API object.Head response contains signature of
object ID rather than signature of object header itself.

In some cases SDK Client provided with signed and prepared
session token. In this case we don't need to change verb
or sign it.

There is a issue when user sends payload chunk to the neofs
node, but node closes connection earlier, e.g. node can return
error as soon as it checked ACL permission and denied request.
In this case client will receive EOF error and it produces
`could not send payload bytes to Put object stream` error, but
in fact there is different error.
If we ignore EOF there then `stream.CloseAndRecv()` return
correct error message later.
