Request forwarding callback should be called only if set since it is an
optional parameter. In GetRangeHash forwarder is never set.
Call `forwarder` function only if it is non-nil. Remove no longer needed
`hashOnly` option.

In current implementation `Object.GetRangeHash` RPC handler forwards range
requests for payload data. Missing request forwarder of the original request
caused NPE during execution.
Do not call request forwarder if payload range hash is requested.

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.

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

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.

Support processing of NetmapEpoch and NetmapLookupDepth X-headers when
processing object read operations. Placement for operations
Get/Head/GetRange/GetRangeHash/Search is built for the epoch specified in
NetmapEpoch X-header (by default latest). Also the specified operations are
processed until success is achieved for network maps from the past up to
NetmapLookupDepth value. Behavior for default values (zero or missing) left
unchanged.
