For this feature which only impact if the target system has a custom
file "/etc/custom_supported_gpus.json"
If the file presents, it will effect packages_for_modalias() and
_is_runtimepm_supported(). Both functions are important when "ubuntu-
driver install" a nvidia driver.
For installing nvidia driver, u-d-c has several test in autopkgtest which
contains:
* different branch type: LTS/PB/NFB/Legacy..
* different version type: 390/470/495/510..
* For this particular feature, we created a new autopkgtest
test_system_driver_packages_force_install_nvidia() which not only secure this
FFE but each version bump.
which contains:
1. Normal case (Stock ubuntu), without /etc/customized_supported_gpus.json in
the system.
2. If /etc/custom_supported_gpus.json contains incorrect json field / format.
3. /etc/custom_supported_gpus.json point to the older version than candidate.
4. /etc/custom_supported_gpus.json point to the same version than candidate.
5. /etc/custom_supported_gpus.json point to a non-exist version of
ubuntu-archive (source list).
and you can see from "buildlog" attachment, all passed as well as
"test_system_driver_packages_force_install_nvidia()"

In NVIDIA new GPU release cycle, NVIDIA ships their new GPUs to OEM/ODM for
production.
In the meantime, NVIDIA usually notify OEM/ODM/Canonical (under NDA) to use a
specific nvidia version to development/production.
NVIDIA and OEN/ODM will announce the next generation combination at
the same time usually when the factory ready to ship the product.
We made Ubuntu as a leading distribution supports many cutting edge
devices, it's time to have an official way to make the nvidia
installation consistent in unannounced (yet) nvidia devices to support
OEM/ODM factory shipment for our growing counterparts.

> mention what testing you've done to see that it works
1. pick a cutting edge nvidia graphic.
2. remove nv-525 from the pool.
3. add ppa, apt update and reboot.
4. check the nv support status:
```
$ ubuntu-drivers list
oem-fix-gfx-nvidia-ondemandmode
libfprint-2-tod1-broadcom
oem-somerville-cinccino-meta
```
5. modify custom file
```
$ cat /etc/custom_supported_gpus.json
{
"chips": [
{
"devid": "0x24BA",
"name": "TEST 24BA",
"branch": "580.1234",
"features": [
"runtimepm"
]
},
{
"devid": "0x25BC",
"name": "TEST 25BC",
"branch": "510",
"features": [
"runtimepm"
]
}
]
}
```
6. make sure the hook works
```
$ ubuntu-drivers list
nvidia-driver-510, (kernel modules provided by nvidia-dkms-510)
oem-fix-gfx-nvidia-ondemandmode
libfprint-2-tod1-broadcom
oem-somerville-cinccino-meta
```
P.S. also tried:
1. wrong json format and it shows
"DEBUG:root:package_get_nv_allowing_driver(): unexpected json detected." when
enables the verbose.
2. try non exist nv driver (e.g. 525, has been remove from the pool) and it
shows "DEBUG:root:nvidia-driver-525 is not in the package pool."
The instruction won't return failed but just do nothing from the hook.
