Add direct update support for static lsp
This is workaround for HONEYCOMB-421 (subtree writers + default update does not work well currently). Fixes HC2VPP-277 (at least basic scenarios). Change-Id: I7659436d6c376bdc63eaa36291d5c08792faad94 Signed-off-by: Marek Gradzki <mgradzki@cisco.com> (cherry picked from commit fc06ca33bc587ba2acff16e59645b3d386aa498d)
