Disable all kappa views / indexing for "backup nodes"

[hackergrrl]

We could skip running indexers for folx running cabal headlessly purely as a backup/sync node, which would make sync faster (no cpu fighting over sync vs indexing) and lower draw on cpu/io.

would this be basically a 'hypercore pinning bot' then? i wonder if we can get away with something as simple as that

[hackergrrl]

More like a 'multifeed pinning bot', since it'd need to support N cores and whatever sync protocol cabal ends up using. In the deeper future, if we go the pubsub route, it'll also need awareness of that too. Maybe by default it'd just hold subscriptions to all public channels, for example.

Much much shorter term, this is just skipping the core.use(...) code that sets up the views.
