nat: T1083: add translation options for persistent/random mapping of address and port
Tested using:
set destination rule 100 inbound-interface 'eth0'
set destination rule 100 translation address '19.13.23.42'
set destination rule 100 translation options address-mapping 'random'
set destination rule 100 translation options port-mapping 'none'
set source rule 1000 outbound-interface 'eth0'
set source rule 1000 translation address '122.233.231.12'
set source rule 1000 translation options address-mapping 'persistent'
set source rule 1000 translation options port-mapping 'fully-random'
