vyos-hostsd: T2583: partial rewrite
- update copyright date - validate incoming JSON data against a schema with voluptuous - add usage help describing internal messages syntax at top of vyos-hostsd - move socket and state file to directory /run/vyos-hostsd - replace jinja2 rendering with vyos.template - move all templates out of the executable into dedicated data/templates dirs - move recursor.conf forward-zones-recurse to forward-zones-file - generate lua-config-file for pdns-recursor with addNTA - support adding custom forward zones for pdns-recursor with optional added NTA and/or recursion-desired - move search_domains from set_host_name to separate add/delete/get commands - unify functions to support abstracting them in the future - track number of internal changes in "changes" variable saved in state file (informational in apply function) - do not apply changes immediately, add apply function that applies all changes (to not reload pdns-recursor excessively for a large set of changes, users must call the apply function once at the end) - add pdns_rec_control function that supports sending arbitrary commands to rec_control (fix pdns-recursor process name that caused the old function to think pdns-recursor was never running) - create /run/powerdns if it doesn't exist (on boot vyos-hostsd starts before pdns-recursor but we need to put our generated conf files there) - abstract specific command functions (add_*/del_*) into general functions to manipulate various types of data in the state variable - add command types: - forward_zones (generate custom forward zones for pdns-recursor) - search_domains (move from set_host_name as dhcp client needs to change them too) - name_server_tags_recursor (to set tags whose nameservers are added to pdns-recursor) - name_server_tags_system (to set tags whose nameservers and search domains are added to /etc/resolv.conf) - change hosts data format to make more sense (move tag from within each host dict to the key for a list of host dicts) - do not remove state file when shut down cleanly, to not lose state when restarting vyos-hostsd service that's then impossible to restore without restarting the whole router - a reboot will remove the state file as it lives in a tmpfs (/run) - remove too verbose info log on every received message - set mode of socket to 770 to secure it against processes not in hostsd group
