=====
Remove the need of accessing handler in NSS unit test
Currently, to wait for handler becomes idle, specific message
is used and the test would wait for condition variable to be
open when the message is processed.
However, this is already done in the HandlerUtils. Thus,
there is no need to post such message manually in the handler.

=====
Remove setHandler in NetworkStatsService
Currently, internal handler is set by setHandler after
constructing NSS object. This was introduced in ag/866187 to
access the handler in the unit test.
However, the design put NSS in a bad situation where all classes
that need handler or executor could not be final and need to be
dynamically allocated in order to get a valid handler.
Thus, since the usage of handler is removed in previous patch,
this change eliminate setHandler by initializing the handler in
the constructor.
