Alex Vanin ca552f53c6 [#115] Check session token validity
Malicious user can stole public session key and use
it by sending request from it's own scope. To prevent
this each session token is signed and signature private
key must be corresponded with owner id in token. Therefore
malicious node cannot impersonate request without private
key to sign token.

GRPC has default message limit of 4MiB. Since every transmitted

This commit introduce transport payload splitter for object
service pipeline. This splitter works with stream response
for methods:

  - object.Get
  - object.Range
  - object.Search
