nat: static mappings in flow hash
Put static mappings in flow hash, drop existing hash tables used for static mappings. Drop refcount variables and use hash table as a single point of truth. Allow creating a static mapping conflicting with dynamic mapping, which will take precedence after dynamic mapping is freed, so that the existing flow can finish transferring data. Type: fix Signed-off-by: Klement Sekera <ksekera@cisco.com> Change-Id: Ieeba691d83a83887d0a0baccd5f3832f66126096
