T4815: Fix various name server config issues
1. When a PPPoE session is connected, `pppd` will update
`/etc/resolv.conf` regardless of `system name-server` option unless `no-peer-dns` is set.
This is because `pppd` vendors scripts `/etc/ppp/ip-up.d/0000usepeerdns` and `/etc/ppp/ip-down.d/0000usepeerdns`,
which updates `/etc/resolv.conf` on PPPoE connection and reverts the change on disconnection.
This PR removes those scripts and adds custom scripts to update name server entries through `vyos-hostsd` instead.
2. There is a typo in `/etc/dhcp/dhclient-enter-hooks.d/04-vyos-resolvconf, which misspells variable name `new_dhcp6_name_servers` as `new_dhcpv6_name_servers`.
This causes IPv6 name server entries in `vyos-hostsd` not updated
when dhclient receives nameservers from DHCPv6.
3. Regular expressions in scripts under `/etc/dhcp/dhclient-enter-hooks.d` and
`/etc/dhcp/dhclient-exit-hooks.d/` are not enclosed in `^$`, so those
IPv4 related branches (like `BOUND`) could be mistakenly executed when an IPv6
reason (like `BOUND6`) is given.
