Libnetwork passes a map[string]any to the bridge driver's Register
function. This forces the daemon to convert its configuration into a
map, and the driver to convert that map back into a struct.
This is unnecessary complexity, and makes it harder to track down where
and how bridge driver configuration fields are set.
Refactor libnetwork to let the daemon register the bridge.Configuration
directly through a new option `OptionBridgeConfig`.
The bridge driver now takes a `Configuration` param that needs no
special treatment.

Since commit 4e246efcd, individual portmappers are responsible for
setting up firewall rules and proxying according to their needs.
This change moves the responsibility back to the bridge driver, removing
unnecessary code duplication across portmappers. For now, only the nat
portmapper takes advantage of this.
This partially reverts commit 4e246efcd.
