v4.0.0 Gluetun

[qdm12]

What's the feature 🧐

There are several pending breaking changes that will simplify the code and allow for faster development.
There is no fixed date really for a v4.0.0 release, but it will ultimately happen.

Changes to be made are listed here:

• Remove FIREWALL_DEBUG in favor of LOG_LEVEL=debug
• Remove Surfshark region retro compatibility (search for // TODO .*v4) and remove RetroLoc from server model
• Split DOT_PRIVATE_ADDRESS in two: ips and cidr ranges
• Rename UNBLOCK to a better name
• ProtonVPN: remove name field from updater code
• Throw out v0 http server
• Remove /v1/openvpn route and have a /vpn, /vpn/openvpn and /vpn/wireguard routes
• MAYBE have the http server as json rpc instead of json rest?
• Change OPENVPN_ENDPOINT_IP + OPENVPN_ENDPOINT_PORT -> OPENVPN_ENDPOINT, same for Wireguard
• Change control server /unbound/ route to /dns
• Change Public iP period == 0 => disabled to a boolean on or off setting
• Merge file and secret file sources together. Use env variable suffix _FILE to define custom paths, and drop _SECRETFILE variables. Each key try can check first in /run/secrets then in /gluetun.
• Storage servers.json: change vpn field to be an array for example ["openvpn", "wireguard"]
• Storage: split servers.json per provider
• Storage: only load as required, to reduce memory footprint
• Server: disable by default
• Remove protonvpn option from VPN_PORT_FORWARDING_PROVIDER since it's now automated and no need to use the custom provider anymore for wireguard.
