Fixed reading whole list/leaf-list using GET/GET-CONFIG RPC

- The source of the issue was in skipping of empty list/leaf-list
  nodes in XMLStreamNormalizedNodeStreamWriter - the NETCONF
  filter structure was created correctly, but it wasn't correctly
  serialized into XML. However, in NETCONF, it is valid to read
  whole list/leaf-list - we must be able to build NormalizedNode
  structure from subtree-filter which "ends" by list/leaf-list.
- Fixed by introduction EmptyListXmlWriter which is responsible
  for serialization of empty list/leaf-list. Other operations
  are delegated to XMLStreamNormalizedNodeStreamWriter
  implementation.

Explicit reading of list keys using subtree filtering

  ask for these fields; see following statement:

  o  If any sibling nodes of the selection node are instance
     identifier components for a conceptual data structure (e.g.,
     list key leaf), then they MAY also be included

- Tool listens for mounted devices with prefix "perf-"
- Notification counter is only applied for devices that end with the following
pattern '*-notif-([0-9]+)', and the number after notif suffix indicates
how many notifications should be counted

- Added option to specify fields that are read from NETCONF device.
  Currently it is possible to only read one whole subtree
  using get/get-config NETCONF RPC. However, NETCONF RFC allows
  more complex subtree filtering including multiple subtrees
  in single RPC.
- It is implemented as:
  1) DOMDataBroker extension - option to create customized
     read-only, read-write transactions, and transaction chains.
  2) NetconfDataTreeService methods - using get(..) and
     getConfig(..) calls.
