📝 Provide a clear and concise description of the issue.

When running an install via config file, it appears that it only looks in /etc/network/interfaces for bridges, and ignores /etc/network/interfaces.d/. This conflicts with use of Proxmox SDN (https://pve.proxmox.com/wiki/Software-Defined_Network)

🔄 Steps to reproduce the issue.

Deploy via config file with an SDN interface (which exists in /etc/network/interfaces.d/ and not /etc/network/interfaces

❌ Paste the full error output (if available).

  ✖️   Bridge 'vlan80' does not exist in /etc/network/interfaces

NOTE: vlan80 exists in /etc/network/interfaces.d/sdn

🖼️ Additional context (optional).

I believe this is the code that builds the interfaces list when using the UI/Menus. Notice it checks all files within /etc/network/interfaces.d/:

ProxmoxVE/misc/build.func

Line 533 in dfa0862

IFACE_FILEPATH_LIST="/etc/network/interfaces"$'\n'$(find "/etc/network/interfaces.d/" -type f)

However, when using a config file, it appears to only check /etc/network/interfaces:

ProxmoxVE/misc/build.func

Line 938 in dfa0862

if grep -q "^iface ${BRG}" /etc/network/interfaces; then

is fixed when #4528 merges.
