Change anonymous func arg for `Iterate`
methods of Storages to `PeerTrustsHandler`

daughter Storage.

In previous implementation node's Object Get/Head/GetRange V2 service
handlers created a new request for each RPC. Now original requests are
re-signed according to API specification. Logical handler abstracts from
this version-dependent logic through `RequestForwarder` callback.

Add `Router` to the reputation server. `Router` is
called on every incoming request and inits `Writer`
that sends `Trust`s to the next route point or
handle(logs in that implementation) them if current
node is the end point of the route.
Rename `onlyKeyRemoteServerInfo` struct for container
to separate it from the same implementation of the
same `ServerInfo` interface for reputation.

Implement reputation `Router` and its constructor,
designed to define where to send local trusts.
Router is based on dependencies that are hidden
behind interfaces, that are declared in the router's
package.

Replace usage of `cache.ClientCache` type with interface with similar
signature. This will further allow overloading clients without affecting the
logic of dependent packages.

Implement in-memory `Storage` which is going to be used to submit the
results of interactions with network members. `Storage` also provides an
iterator interface, so the component can be used in `Controller`.
Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
Implement `Controller` designed to analyze the values collected by the local
node (the source is hidden behind Writer/WriterProvider interfaces) and
transfer them to the destination (hidden behind Iterator / IteratorProvider
interface).

At object.Put operation node does not transfer any
data. It is done in the stream inside, so we should
register duration from `object.Put` invocation until
`CloseAndRecv` on the stream.
Signed-off-by: Alex Vanin <alexey@nspcc.ru>
We can't rely on object size in the header because it
might be omitted on initial put or it can be 0xFF.. on
streaming data.

Because options are not used when client is already in cache
providing them to shared cache is misleading at best.
In the worst case `dial_timeout` is set randomly (because of race
condition) which can lead to one service having `dial_timeout` of
another. Thus we set default client creation options when cache is
created.

Re-compile protobuf definition of Control service. Implement required

Implement route Builder interface on wrapper over the container placement
builder, Component implies exactly one transfer to each of the most weight
nodes of the container (according to some weighing algorithm).

storage nodes.

Implement a component for transmitting the value of the used container space
along a route defined in the system. Implement WriterProvider interface on
it. By implementation, it is the link between the route planner and the
point-to-point transmitter, and abstracts from the implementation of both of
them. In the future, this implementation will be used as a transmitter of
local estimates of storage nodes among themselves.
