Limit Guest Network per project/account, etc.

[hosmir]

As an Admin/Operator I would like to limit the number of Guest Networks a user can have.

In our multi-tenant environment, each Guest Network of type Shared gives the user VMs a public IP. And the option that already exists for limiting public IPs does not work for our use case because of our architecture.
I have implemented most of the code in a private branch and it is currently going through some internal testing. I would like to know if this is something you want implemented in the upstream branch so I can go ahead and create a PR for it.

@hosmir, on accounts you can set a limit to the number of networks they can create. If this is not the functionality you mean, then we are certainly interested in your proposal/code.

@hosmir
Is it a typo, did you mean Isolated network (not Shared) ?

Tenants are free to create and use many networks if they wish, only the public IPs (that they attain via assigning a shared guest network to their VMs) should be limited.

I will tidy up the code in the coming days and since I implemented the code for v4.17.2, I will need to adapt it to the main branch from upstream. Will open a PR the soonest I can.
Thanks

No, I actually meant shared networks, since they are how tenants can assign a public IP to their VMs from pools of predefined shared networks.
