CLI route commands

[EnigmaCurry]

To create layer 7 / layer 4 routes you have to go into the traefik config and find Advanced routing, and you're three menus deep. Let's make a CLI command to do it in one step.

## List Layer 7 and Layer 4 routes:
$ sentry route list

## Manage Layer 7 routes:
$ sentry route add DOMAIN DEST_IP DEST_PORT [--proxy-protocol true] [--restart true/false]
$ sentry route remove DOMAIN [--restart true/false]

## Manage Layer 4 routes with --layer4:
$ sentry route add ENTRYPOINT DEST_IP DEST_PORT --layer4 [--proxy-protocol true] [--restart true/false]
$ sentry route remove ENTRYPOINT --layer4 [--restart true/false]

## It should respond to the following environment variables found in .env_{CONTEXT}:
## Turns on proxy protocol by default for new routes:
DEFAULT_CLI_ROUTE_LAYER_7_PROXY_PROTOCOL=true
DEFAULT_CLI_ROUTE_LAYER_4_PROXY_PROTOCOL=true

$ d route
Manage Traefik routes

Usage: d route {list|set|remove} ARGS [options]

Subcommands:
  list      - List all routes
  set       - Set a new route or update an existing one
      set (DOMAIN|ENTRYPOINT) DEST_IP DEST_PORT [OPTIONS...]
  remove    - Remove an existing route
      remove (DOMAIN|ENTRYPOINT) [OPTIONS...]

Options for set / remove:
  --layer7                       - create a Layer 7 route (default)
  --layer4                       - create a Layer 4 route
  --restart [true/false]         - Automatically restart Traefik or not
  --proxy-protocol [true/false]  - Turn on Proxy Protocol for the route or not
  --protocol [udp/tcp]           - TCP (default) or UDP

Examples:

List all routes:

 d list

Set Layer 7 route to HTTP(s) destination 192.168.1.2:8000
using the context default proxy protocol option:

 d route set --layer7 whoami.example.com 192.168.1.2 8000

Set Layer 7 route to HTTP(s) destination 192.168.1.2:8000
forcing the proxy protocol option ON:

 d route set --layer7 whoami.example.com 192.168.1.2 8000 --proxy-protocol true

Remove Layer 7 route:

 d route remove --layer7 whoami.example.com

Set Layer 4 route to TCP destination 192.168.1.2:9000
using an existing entrypoint named 'test'
using the context default proxy protocol option (or set --proxy-protocol true):

 d route set --layer4 test 192.168.1.2 9000

Remove Layer 4 route:

 d route remove --layer4 test

All examples will ask to restart Traefik, unless --restart true/false is set.
