Since in case of no errors during processing we should call finalize, to
ensure that it will not be called from dtor.

Since I saw the following:

    0. DB::WriteBufferFromOStream::nextImpl()
    1. DB::WriteBufferFromHTTPServerResponse::nextImpl()
    2. DB::WriteBufferFromHTTPServerResponse::finalize()
    3. DB::WriteBufferFromHTTPServerResponse::~WriteBufferFromHTTPServerResponse()
    4. DB::StaticRequestHandler::handleRequest(Poco::Net::HTTPServerRequest&, Poco::Net::HTTPServerResponse&)
    5. Poco::Net::HTTPServerConnection::run()
    6. Poco::Net::TCPServerConnection::start()

9bcc5a6175 Support interserver credential rotation 
Restarting a server instance to change the interserver password results
in many replicas being out of sync until all clusters are using the new
credential.

This commit adds dynamic credential loading for both the client
(Replicated* tables) and server (InterserverIOHTTPHandler).

This commit also adds the ability to rotate credentials, i.e. accept more
than one credential during a credential change.

state0 (no auth):

    <interserver_http_credentials />

state1 (auth+allow_empty migration):

    <interserver_http_credentials>
        <user>admin</user>
        <password>222</password>
        <allow_empty>true</allow_empty>
    </interserver_http_credentials>

state2 (auth+new admin password migration):

    <interserver_http_credentials>
        <user>admin</user>
        <password>333</password>
        <users>
            <admin>222</admin>
        </users>
    </interserver_http_credentials>

5b3ab48861 More forward declaration for generic headers 
The following headers are pretty generic, so use forward declaration as
much as possible:
- Context.h
- Settings.h
- ConnectionTimeouts.h
(Also this shows that some missing some includes -- this has been fixed)

And split ConnectionTimeouts.h into ConnectionTimeoutsContext.h (since
module part cannot be added for it, due to recursive build dependencies
that will be introduced)

Also remove Settings from the RemoteBlockInputStream/RemoteQueryExecutor
and just pass the context, since settings was passed only in speicifc
places, that can allow making a copy of Context (i.e. Copier).

Approx results (How much units will be recompiled after changing file X?):

- ConnectionTimeouts.h
  - mainline: 100

- Context.h:
  - mainline: ~800
  - patched:  415

- Settings.h:
  - mainline: 900-1K
  - patched:  440 (most of them because of the Context.h)
