UI won't start if IPv6 is disabled in kernel

[Raboo]

Describe the bug
The OpenCost UI won't start if you have disabled ipv6 in the kernel boot cmdline.

$ cat /proc/cmdline
BOOT_IMAGE=(hd0,gpt2)/vmlinuz-5.14.0-427.31.1.el9_4.x86_64 root=UUID=25f86933-0567-4e26-ac6b-9676112eaf45 ro ipv6.disable=1

To Reproduce

1. Disable IPv6. Add "ipv6.disable=1" to your grub kernel parameters.
2. Reboot your k8s cluster
3. Run OpenCost with UI enabled.

Expected behavior
An option to disable the IPv6 listen line in nginx.conf.
