Summary:
Previously, the network stack `communication::Server` accepted connections and
assigned them statically in a round-robin fashion to `communication::Worker`.
That meant that if two compute intensive connections were assigned to the same
worker they would block each other while the other workers would do nothing.
This implementation replaces `communication::Worker` with
`communication::Listener` which holds all accepted connections in one pool and
ensures that all workers execute all connections.

Summary:
With this patch the number of packets for a simple RPC call is lowered
from 22 to 12 (45% reduction). The number of packets for the Bolt protocol
is lowered from 26 to 18 (30% reduction).
Impact on the Bolt protocol will be a constant of ~ 8 packets less per
connection, while the impact on the RPC protocol will be approximately
a 45% reduction overall.
