Currently, we can not set the metric of routes in dhcp.
It's ok if there is only a network interface.
But if there are multiple network interfaces, and both have a default route,
We need to set the metric of the route to make the traffic
go through the correct network interface.
For host-local and static, we can set the metric with the route.priority option.
But there is no such option for dhcp.

* Use of Table ID in IPAM

* SBR: option to pass the table id
Using the option to set the table number in the SBR meta plugin will
create a policy route for each IP added for the interface returned by
the main plugin.
Unlike the default behavior, the routes will not be moved to the table.
The default behavior of the SBR plugin is kept if the table id is not set.

A dot is a valid character in interface names and is often used in the
names of VLAN interfaces. The sysctl net.ipv6.conf.<ifname>.disable_ipv6
key path cannot use dots both in the ifname and as path separator.
We switch to using / as key path separator so dots are allowed in the
ifname.
This works because sysctl.Sysctl() accepts key paths with either dots
or slashes as separators.
Also, print error message to stderr in case sysctl cannot be read
instead of silently hiding the error.

Utility functions created for common PrevResult checking
Fix windows build
Namespace creation had an unergonomic interface and isn't used, except
for testing code. Remove it; downstream users should really be creating
their own namespaces
If CNI is about to configure an IPv6 address, make sure IPv6 is not
disabled through the "disable_ipv6" sysctl setting.
This is a workaround for Docker 17.06 and later which sets
disable_ipv6=1 for all interfaces even if ipv6 is enabled in Docker.
This change improves the performance of the ipam.ConfigureIface.
Some plugins are slow because of the ip.SettleAddress in ipam.ConfigureIface.
It seems to be only needed for IPv6, so should be skipped if only IPv4 is used.
- start list of linux_only plugins; ignore them when testing on Windows
- Isolate linux-only code by filename suffix
- Remove stub (NotImplemented) functions
- other misc. fixes for Windows compatibility
* Wait for addresses to leave tentative state before setting routes
* Enable forwarding correctly
* Set up masquerading according to the active protocol
