Add subsystem benchmarks for availability-distribution and biftield-distribution (availability write) (#2970)

Introduce a new test objective : `DataAvailabilityWrite`.

The new benchmark measures the network and cpu usage of
`availability-distribution`, `biftield-distribution` and
`availability-store` subsystems from the perspective of a validator node
during the process when candidates are made available.

Additionally I refactored the networking emulation to support bandwidth
acounting and limits of incoming and outgoing requests.
