T1797: Add initial vpp configuration

Add initial configuration mode for VPP (PoC)

set vpp cpu corelist-workers '2'
set vpp cpu main-core '1'
set vpp interface eth1 num-rx-desc '256'
set vpp interface eth1 num-rx-queues '512'
set vpp interface eth1 num-tx-desc '256'
set vpp interface eth1 num-tx-queues '512'
set vpp interface eth1 pci '0000:02:00.0'
set vpp interface eth1 rx-mode 'polling'
set vpp interface eth2 pci '0000:08:00.0'

Limitation:
  - 'set vpp interface ethX pci auto' works only per first
    commit, then interface detached from default stack and creates
    tun interface 'ethX' to communicate with default stack. In this
    case we can't get PCI address via ethtool for 'tun' interfaces.
    But we can set pci address manualy.

  - Interface sync between default stack and VPP-DPDK stack
    After vpp change it doesn't trigger iproute2 for changes
    (should be written later)

I.e. if we change something in vpp per each commit it restarts
vpp.service it gets empty interface config as we don't configure vpp
directly and it should be configured via iproute2
But then if we do any change on interface (for example description)
it gets IP address, MTU, state, etc.
