nat: nat44 enable/disable dynamic config
This patch changes initialization and configuration of NAT
plugin. Instead of allocating data structures at vpp plugin
initialization phase allocation and configuration happens
after calling enable API or CLI call. This reduces base VPP
memory footprint and also enables dynamic reconfiguration
of the NAT plugin.
Type: improvement
