Prefetch Serve expired behavior per cache

[ashok athukuri]

Hello All,

I am a newbie for unbound, please apologize if my question is wrong or my
understanding is wrong.

I see below variables make unbound to use a single configuration for all
cache resolvers.
As these variables are global and don't bind with any unbound context or
configuration for each cache

I wonder how to solve this problem? as I need different cache conf for
different cache resolvers.
