Prepare snap server client test scenario cont3 (#1491)
* Handle last/all node(s) proof conditions at leaf node extractor

detail:
  Flag whether the maximum extracted node is the last one in database
  No proof needed if the full tree was extracted

* Clean up some helpers & definitions

details:
  Move entities to more plausible locations, e.g. `Account` object need
  not be dealt with in the range extractor as it applies to any kind of
  leaf data.

* Fix next/prev database walk fringe condition

details:
  First check needed might be for a leaf node which was done too late.

* Homogenise snap/1 protocol function prototypes

why:
  The range arguments `origin` and `limit` data types differed in various
  function prototypes (`Hash256` vs. `openArray[byte]`.)

* Implement `GetStorageRange` handler

* Implement server timeout for leaf node retrieval

why:
  This feature leaves control on the server for probably costly action
  invoked by the network

* Implement maximal reply size for snap service

why:
  This feature leaves control on the server for probably costly action
  invoked by the network.
