polkadot: disable block authoring backoff on production networks (#2510)

Browse Source 
Currently the polkadot node will backoff from block authoring if
finality starts lagging. This PR disables this mechanism on production
networks (polkadot and kusama) and adds a flags to optionally force
enabling it.
