[stork-users] Stork managing Kea backend ( database )

[Slawek Figiel]

Hello Vadim!

The "subnet_cmds" hook is required to modify the subnets and shared 
network in Stork. Support for the "cb_cmds" hook is under development.

I recommend you keep the subnet_cmds" hook loaded and disable the 
confusing checker.

I opened https://gitlab.isc.org/isc-projects/stork/-/issues/1654 to 
remove it, as the suggestion is confusing. This checker was implemented 
when we didn't support the subnet hook.

Regards,
Slawek Figiel
