Wrap functions at `pkg/errors` return nil if error argument
was nil. fmt.Errorf always returns error so we need to add
missing error checks to the code.

To enable TLS support we can't operate with IP addresses directly.
Certificates are issued with host names so it is required to
pass them into RPC client. DNS resolving should be done by transport
layer and not be a part of node. Therefore `IPAddrString` usage is
removed from code.

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.

The lifetime of an object can be limited by specifying a correspondin
well-known attribute. Node should refuse to save expired objects.
Checking objects in FormatValidator is extended with an expiration attribute
parsing step.

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.

With one tombstone for split objects we can't simply
place it in container. We should inform all nodes that
store split objects of removed original object.
