Subject: nat: T538: Add static NAT one-to-one

Ability to set static NAT (one-to-one) in one rule

set nat static rule 10 destination address '203.0.113.0/24'
set nat static rule 10 inbound-interface 'eth0'
set nat static rule 10 translation address '192.0.2.0/24'

It will be enough for PREROUTING and POSTROUTING rules
Use a separate table 'vyos_static_nat' as SRC/DST rules and
STATIC rules can have the same rule number
