723ba5ee45 [#227] netmap: Do not use intermediate types for placement 
Support preprocessing within the `NodeInfo` type. Provide methods for
placement directly from the `NodeInfo` type. Returns slice of slices of
`NodeInfo` from placement methods of `Netmap`. Remove no longer needed
`Node` and `Nodes` types.

ea5da31bd2 [#109] netmap: add 1 more test in JSON 
Move `PlacementPolicy_ProcessSelectors` test. It tests how good
nodes were grouped into buckets after selection, but we can still query
full results and check them.

3edaf9ecb6 netmap: sort buckets by HRW value 
If weights for some buckets are equal, result depends on the
initial positions of buckets in slice. Thus we sort buckets by value
using hash of the first node as a have for the whole bucket.
This is ok, because buckets are already sorted by HRW.

e7ac7f339e [#82] netmap: Add functionality for working with subnets 
* Implement `NodeInfo.EnterSubnet` method which adds node's subnet.
  * Implement `NodeInfo.IterateSubnets` which behaves similar to
  eponymous function from neofs-api-go/v2.
  * Implement `BelongsToSubnet` which checks if `NodeInfo` describes the
  node belonging to a specific subnet.
