Neels Janosch Hofmeyr 091603c4a4 deprecate cfg 'nft rule tunmap append'
Subsequent patch will refactor the tunmap nft ruleset. Instead of
adapting the 'tunmap append' feature to the new ruleset, rather drop
this feature entirely.

The 'nft rule tunmap append' was intended for enabling 'trace' in the
nft ruleset. However, the same can be achieved via the nft cmdline tool.
For example:

 sudo nft 'add chain filter trace_chain { type filter hook prerouting priority -301; }'
 sudo nft 'add rule filter trace_chain meta nftrace set 1'

table-name Set the nft inet table name to create and place GTP tunnel forwarding chains in (as in 'nft add table inet foo'). If multiple instances of osmo-upf are running on the same system, each osmo-upf must have its own table name. Otherwise the names of created forwarding chains will collide. The default table name is "osmo-upf".
