The commit contains fix for the issue reported in
https://github.com/moby/moby/issues/33415 and
https://github.com/docker/libnetwork/issues/1772. With the
feature introduced to support local scope networks in swarm
mode the network configuration to include ipam driver was overriden
in libnetwork. This has been removed with this fix which will allow
ipam-driver option to be used for task allocation

Allow users to configure firewall policies in a way that persists
docker operations/restarts. Docker will not delete or modify any
pre-existing rules from the DOCKER-USER filter chain. This allows
the user to create in advance any rules required to further
restrict access from/to the containers.

- It specifies whether the network driver can
provide containers connectivity across hosts.
- As of now, the data scope of the driver was
being overloaded with this notion.
- The driver scope information is still valid
and it defines whether the data allocation
of the network resources can be done globally
or only locally.
- With the scope network option, user can now
force a network as swarm scoped
regardless of the driver data scope.
- In case the network is configured as swarm scoped,
and the network driver is multihost capable,
a network DB instance will be launched for it.

- They are configuration-only networks which
can be used to supply the configuration
when creating regular networks.
- They do not get allocated and do net get plumbed.
Drivers do not get to know about them.
- They can be removed, once no other network is
using them.
- When user creates a network specifying a
configuration network for the config, no
other network specific configuration field
is are accepted. User can only specify
network operator fields (attachable, internal,...)
- They do not need to have a driver field, that
field gets actually reset upon creation.

This change cleans up the SetClusterProvider method.
Swarm calls the SetClusterProvider to pass to libnetwork the pointer
of the provider from which libnetwork can fetch all the information to
initialize the internal agent.
The method can be and is called multiple times passing the same value,
with the previous logic that was erroneusly spawning multiple go routines that
were making possiblea race between an agentInit and an agentClose.
The new logic aims to disallow it by checking for the provider passed and
ensuring that if the provider is already present there is nothing to do because
there is already an active go routine that is ready to process cluster events.
Moreover a patch on moby side takes care of clearing up the Cluster Events
dispacthing using only 1 channel to handle all the events types.
This will also guarantee in order event handling because now all the events are
piped into one single channel.

- Now that docker has the code to release the ingress
network, have docker do the release on cluster leave
and on graceful daemon shutdown.
This is a cleaner approach in line with the cleanup
triggered by who created the resource and will avoid
races on ingress network removal as revealed by the
docker tests.

With the introduction of networkdb, the node discovery events were not
sent to the drivers. This commit generates the node discovery events and
sents it to the drivers interested in it.

This fix tries to fix logrus formatting by removing `f` from
`logrus.[Error|Warn|Debug|Fatal|Panic|Info]f` when formatting string
is not present.
Also fix import name to use original project name 'logrus' instead of
'log'

As part of daemon init, network and ipam drivers are passed a
pluginstore object that implements the plugin/getter interface. Use this
interface methods in libnetwork to interact with network plugins. This
interface provides the new and improved pluginv2 functionality and falls
back to pluginv1 (legacy) if necessary.
