strings.ReplaceAll(s, old, new) is a wrapper function for
strings.Replace(s, old, new, -1). But strings.ReplaceAll is more
readable and removes the hardcoded -1.

Windows Server 2016 (RS1) reached end of support, and Docker Desktop requires
Windows 10 V19H2 (version 1909, build 18363) as a minimum.
This patch makes Windows Server RS5 / ltsc2019 (build 17763) the minimum version
to run the daemon, and removes some hacks for older versions of Windows.
There is one check remaining that checks for Windows RS3 for a workaround
on older versions, but recent changes in Windows seemed to have regressed
on the same issue, so I kept that code for now to check if we may need that
workaround (again);

These are failing in CI because something is not enabled.
Its not clear that these tests ever worked because they were not
actually running while in the libnetwork repo, which was only testing
Linux.

After moving libnetwork to this repo, we need to update all the import
paths for libnetwork to point to docker/docker/libnetwork instead of
docker/libnetwork.
This change implements that.

In windows HNS manages IPAM. If the user does not specify a subnet, HNS will choose one
for them. However, in order for the IPAM to show up in the output of "docker inspect",
we need to update the network IPAMv4Config field.

For overlay, l2bridge, and l2tunnel, if the user does not specify a host port, windows driver will select a random port for them. This matches linux behavior.
For ics and nat networks the windows OS will choose the port.

When dockerd.exe is not stopped cleanly (such as when Windows is
restarted), the endpoints are not cleaned up. When using a transparent
network, the endpoint IPv4 address is blank. When dockerd.exe starts up
again, libnetwork restores the endpoint, which would not have been
stored on a clean shutdown of dockerd.exe. That fails because the IPv4
address is blank. This change warns instead of failing.

The previous code used string slices to limit the length of certain
fields like endpoint or sandbox IDs. This assumes that these strings
are at least as long as the slice length. Unfortunately, some sandbox
IDs can be smaller than 7 characters. This fix addresses this issue
by systematically converting format string calls that were taking
fixed-slice arguments to use a precision specifier in the string format
itself. From the golang fmt package documentation:
For strings, byte slices and byte arrays, however, precision limits
the length of the input to be formatted (not the size of the output),
truncating if necessary. Normally it is measured in runes, but for
these types when formatted with the %x or %X format it is measured
in bytes.
This nicely fits the desired behavior: it will limit the number of
runes considered for string interpolation to the precision value.

agent.pb.go is unchanged, but the files in networkdb and drivers
are slightly different when regenerated using the current versions
of protoc and gogoproto. This is probably because agent.pb.go
was last regenerated quite recently, in February 2018, whereas
networkdb.pb.go and overlay/overlay.pb.go were last changed in 2017,
and windows/overlay/overlay.pb.go was last changed in 2016.

- 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.

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'

With the introduction of a driver generic gossip in libnetwork it is not
necessary for drivers to run their own gossip protocol (like what
overlay driver is doing currently) but instead rely on the gossip
instance run centrally in libnetwork. In order to achieve this, certain
enhancements to driver api are needed. This api aims to provide these
enhancements.
The new api provides a way for drivers to register interest on table
names of their choice by returning a list of table names of interest as
a response to CreateNetwork. By doing that they will get notified if a
CRUD operation happened on the tables of their interest, via the newly
added EventNotify call.
Drivers themselves can add entries to any table during a Join call by
invoking AddTableEntry method any number of times during the Join
call. These entries lifetime is the same as the endpoint itself. As soon
as the container leaves the endpoint, those entries added by driver
during that endpoint's Join call will be automatically removed by
libnetwork. This action may trigger notification of such deletion to all
driver instances in the cluster who have registered interest in that
table's notification.

Because overlay is a builtin driver and global allocation of overlay
resources is probably going to happen in a different node (a single
node) and the actual plumbing of the network is probably going to happen
in all nodes, it makes sense to split the functionality of allocation
into two different packages. The central component(this package) only
implements the NetworkAllocate/Free apis while the distributed
component(the existing overlay driver) implements the rest of the driver
api. This way we can reduce the memory footprint overall.
