Dan Williams a49f908168 ip: place veth peer in host namspace directly
Instead of moving the host side of the veth peer into the host
network namespace later, just create it in the host namespace
directly.

Edward Haas a3cde17fc0 bridge: Add mac field to specify container iface mac
Controlling the mac address of the interface (veth peer) in the
container is useful for functionalities that depend on the mac address.
Examples range from dynamic IP allocations based on an identifier (the
mac) and up to firewall rules (e.g. no-mac-spoofing).

Enforcing a mac address at an early stage and not through a chained
plugin assures the configuration does not have wrong intermediate
configuration. This is especially critical when a dynamic IP may be
provided already in this period.
But it also has implications for future abilities that may land on the
bridge plugin, e.g. supporting no-mac-spoofing.

The field name used (`mac`) fits with other plugins which control the
mac address of the container interface.

The mac address may be specified through the following methods:
- CNI_ARGS
- Args
- RuntimeConfig [1]

The list is ordered by priority, from lowest to higher. The higher
priority method overrides any previous settings.
(e.g. if the mac is specified in RuntimeConfig, it will override any
specifications of the mac mentioned in CNI_ARGS or Args)

[1] To use RuntimeConfig, the network configuration should include the
`capabilities` field with `mac` specified (`"capabilities": {"mac": true}`).
