Speed up YangLibrarySchemaYangSourceProvider

We can potentially have a lot of schemas for a mount point, hence
we should be using an immutable map. Also do not use Map.contains()
before issuing a Map.get(), saving one lookup.

(cherry picked from commit 332280c42305db34b1b1ca0b59f59964cb5e305f)

Do not instantiate NormalizedNodes for filter

Using ImmutableNodes.fromInstanceId() does not work for leaf nodes,
as we do not have a value, which violates LeafNode contract -- leading
to an IllegalStateException when a user attempts to read() a single
leaf via a transaction.

As it turns out, this is completely unnecessary, as all we are doing
is iterating through the temporary NormalizedNode and creating
NormalizedNodeStreamWriter events based on that.

This patch replicates ImmutableNodes.fromInstanceId() logic, but
simplifies it for this particular task, short-cutting NormalizedNode
creation and emitting events directly as we are iterating over
the YangInstanceIdentifier.

NECONF-524 : Setting the netconf keepalive logic to be more proactive.

https://jira.opendaylight.org/browse/NETCONF-524

When a NETCONF device loses connection with the controller in exceptional
conditions such as the management interface going down, underlying TCP
connection would not be closed as there will be no fin packet exchange or
reset. At this point NETCONF state will be set as connected until the
underlying OS determines the connection is stale which can happen after
considerable amount of time. This fix makes the Keepalive packets more
proactive to determine such conditions.This fix also sets the listener
properly which is required for this fix as well.

Make RuntimeRpc revision aware

Do not use SchemaContext.findModule(URI),
which looks for a module instance with specified namespace
and no revision.
Such lookup fails for modules with revision defined.

Instead (as already done in AbstractEdit)
use SchemaContext.findModules and take the newest module
if more than one module with the same namespace is found.

Fix default schema cache failures

We've these seen intermittent failures on jenkins:

 Caused by: java.lang.IllegalArgumentException: Unable to create cache directory at cache/schema
     at com.google.common.base.Preconditions.checkArgument(Preconditions.java:210)
     at org.opendaylight.yangtools.yang.model.repo.util.FilesystemSchemaSourceCache.<init>(FilesystemSchemaSourceCache.java:74)
     at org.opendaylight.netconf.topology.AbstractNetconfTopology.<clinit>(AbstractNetconfTopology.java:149)

In FilesystemSchemaSourceCache"

  if (!storageDirectory.exists()) {
      checkArgument(storageDirectory.mkdirs(), "Unable to create cache directory at %s",
              storageDirectory);
  }

mkdirs returns false if the dir/file already exists - this seems the likely reason
in this case even though it checks exists() just prior. This scenario could happen
if there's a race where some other component interleaves and creates the dir in
between the exists and mkdirs calls.

To protect against this sceniario, AbstractNetconfTopology and NetconfTopologyUtils
were changed to retry if FilesystemSchemaSourceCache throws an IAE. Also they no
longer fail class initialization on failure.

Convert ProxyDOMDataBroker tx creation to async

ProxyReadWriteTransaction was modified to take the ActorRef
Future from the tx creation message and add a callback when
complete. Transaction operations prior to completion are
queued and replayed to a ProxyTransactionFacade instance
once the Future is complete. For successful completion, an
ActorProxyTransactionFacade is created that interfaces
with the master ActorRef. On failed Future, a
FailedProxyTransactionFacade is created that returns a
failed Future for read, exists and commit operations.

The ProxyReadAdapter and ProxyWriteAdapter were removed
in lieu of ProxyTransactionFacade which combines the
read/write operations for simplicity.

Some simple actor response messages,
eg NewWriteTransactionReply, were removed in lieu of
returning the payload or exception via
akka.actor.Status.Success or akka.actor.Status.Failure.
This simplifies caller response handling as akka
automatically unwraps Success and Failure in callbacks
and synchronous await.

UTs were added, modified and removed corresponding to
the changes.
