nat: remove nat44-ed relation between SM and addr
Change [1] put static mappings in flow hash. This change also broke relationship between nat pool addresses and static mappings. Port and address are no longer reserved in nat pool address records for a new static mapping. Because of this change both nat objects and their configuration can function independently. This change also removed already broken logic of having static-mapping-only configuration. In this patch i have cleaned up and removed unnecessary logic for static mapping configuration functions, address configuration functions, interface configuraiton functions and all callback functions used for resolving interface address bound records. No more viable configuration option static-mapping-only is also removed because there is no more option to run traffic through vpp for static mappings without having flow hash table allocated. Instead user is now able to create static mapping records without using nat pool addresses. Fixed and improved management of required fib entries (ensuring VPP will reply to ARP for all external addresses on outside interfaces) through holding a refcount for their creation and removal.
