nat: nat44-ei configuration improvements
nat44-ed core configuration improvements & fixes [0-5] adjusted for nat44-ei plugin. Improvements: * repeating code converted to functions * simplified functions used for pool address, static mapping and interface configuration. Clean up: * remove obsolete code and logic persisted after plugin separation from old SNAT plugin. Fixes: * [0] return correct API behavior changed in [5] Type: improvement [0] https://gerrit.fd.io/r/c/vpp/+/33622 [1] https://gerrit.fd.io/r/c/vpp/+/33431 [2] https://gerrit.fd.io/r/c/vpp/+/33337 [3] https://gerrit.fd.io/r/c/vpp/+/33249 [4] https://gerrit.fd.io/r/c/vpp/+/32796 [5] https://gerrit.fd.io/r/c/vpp/+/32951 Signed-off-by: Filip Varga <fivarga@cisco.com> Change-Id: Ie197faa576cb49acb3d218f14e00cb7d13ad9342
