[BUG] some broken options in debian_eth.jinja for /etc/network/interfaces

[tigpas]

Description
This Bug report extend the bug #58195. The last refactor (5abe823) of salt/templates/debian_ip/debian_eth.jinja broke some options, like {,pre,post}_{up,down}_cmds.

Setup

linux_interface_eno1:
  network.managed:
  - name: eno1
  - enabled: True
  - type: eth
  - proto: manual
  - up_cmds:
    - /bin/up_cmd1
    - /bin/up_cmd2
  - pre_up_cmds:
    - /bin/pre_up_cmd1
    - /bin/pre_up_cmd2
  - post_up_cmds:
    - /bin/post_up_cmd1
    - /bin/post_up_cmd2
  - down_cmds:
    - /bin/down_cmd1
    - /bin/down_cmd2
  - pre_down_cmds:
    - /bin/pre_down_cmd1
    - /bin/pre_down_cmd2
  - post_down_cmds:
    - /bin/post_down_cmd1
    - /bin/post_down_cmd2

Steps to Reproduce the behavior
salt-call state.apply test + cat /etc/network/interfaces

auto eno1
iface eno1 inet manual

Expected behavior
cat /etc/network/interfaces

auto eno1
iface eno1 inet manual
    up /bin/up_cmd1
    up /bin/up_cmd2
    down /bin/down_cmd1
    down /bin/down_cmd2
    pre-up /bin/pre_up_cmd1
    pre-up /bin/pre_up_cmd2
    post-up /bin/post_up_cmd1
    post-up /bin/post_up_cmd2
    pre-down /bin/pre_down_cmd1
    pre-down /bin/pre_down_cmd2
    post-down /bin/post_down_cmd1
    post-down /bin/post_down_cmd2

@tigpas Thanks for this patch! I ran into the same problem (#58210) on FreeBSD 11.3, using salt-ssh 3001.1. Your patch solved the problem.
