Allow fine control on failover connection/s

[wellloaded]

I can see the current release comes with some sort of internal connection failover, which is great. Something I suggested a while ago, and I'm happy to see it implemented.

What I propose you now implement is a user control on how the failover sequence should be attempted by the client.

I'm talking about a simple drop down list that can be reorg at user whish. e.g. connections that are available to the client (Internal WS, custom wireguard, custom OpenVPN, etc), allowing the user to be grouped into a single failover object list. This object can have a list of connections that the users defined in whichever order hi/she defines.

You could also introduce a pre-empt function to reattempt a connection to the higher priority in the list ever N minutes or so.

Thanks
