Subject: interfaces: T3090: migrate adjust-mss from "firewall options" to
 "interface" level

Getting rid of "set firewall options" and move it from:

set firewall options interface ethX adjust-mss 1400
set firewall options interface ethX adjust-mss6 1400

to:

set interfaces ethernet ethX ip adjust-mss 1400
set interfaces ethernet ethX ipv6 adjust-mss 1400

In addition add an extra option called clamp-mss-to-pmtu instead of a value.
