30bd4038cf Splits network units into separate headers.
This CL moves the network units files into a separate folder with a
separate BUILD file. It also splits the units into separate files.
This prepares for moving all or some of the units to somewhere that
can be accessed by more components.

342695d068 Removes network ostream operators.
The ostream operators does not work consistently with gtest since the
definitions would have to be included before the first include of gtest.
This is tricky to ensure and the end result is that the operators will
sometimes work and sometimes not without obvious explanations.
To avoid causing confusing behavior, this CL removes the operators
pending a better solution.

a73f8161aa Removing static initializers for BBR.
The static initializers caused issues with chromium build. This should
fix it for now.

ae9057831f Removed observer from network controller interface.
Moving the responsibility for calling callbacks from implementations
of NetworkControllerInterface to SendSideCongestionController. This
decreases the coupling and makes the callbacks more explicit.

2808ae99f8 Adds BBR network controller field trial.
This CL adds a field trial to enable the BBR congestion control method.
Since BBR is only implemented to handle per packet feedback,
SendSideCongestionController is modified to recreate network controllers
when the packet feedback availability changes and the BBR experiment is
enabled.

This also means that the periodic task used for process updates in the
network controllers has to recreated.

63b48df334 Removed static const network units.
Static const objects can cause what's called a "static initialization
order fiasco". This CL removes the statically initialized network units
in favor of constexpr defined versions available via static functions.

883f470d60 Adding DataTransferTracker class for BBR.
This class is completely new and tracks data transfer in a slightly
different way compared to the BBR implementation in QUIC. The
fundamental change is that receive time is used rather than packet
index to identify the packets over which data rates should be
calculated.

This is part of a series of CLs adding a network controller based on
the BBR congestion control method. The code is based on the QUIC BBR
implementation in Chromium.
