Channel profiles for Automatic fee settings

[whizz]

The Autofee feature is great, but currently supports either using default values for settings, or set them specifically for each channel. But it's quite common that there are channels which have similar flow characteristics. As an example, there are known liquidity sinks, where you might want to set higher fees or on the other hand, you might have some friends where you want to keep low fees, but still want to manage them in bulk.

This could be solved by introducing something like channel profiles. Each channel can be assigned a profile attribute. Initially, all channels would be assigned the "Default" profile. The operator can create multiple profiles, such as "Sink", "Exchange" or "Friend" and set all the parameters in them.

To make things backward compatible, the attributes can still be overridden on individual channel basis. Internally, I can imagine a solution that each individually managed channel would have their own profile, which would be marked as private, so that it cannot be assigned to any other channel.

Hello, thanks for the suggestion. From my experience all sinks are not equal: some need 1000 ppm, some 4000, etc. Same with sources. I no longer run a node with many channels, so not motivated to add this level of complication. But if others agree feel free to PR.
