These are high level configuration values, that need to be consistent within a given execution. Setting them as default value at such a low level is a footgun risk.
Concepts are being mixed up between the global network config (static vs auto sharding), that needs to be the same of all nodes in the network, individual node configuration (eg relay node subscribing to a given shard), and the routing characteristic of a specific message (eg pubsub topic, shard).
This stops proper configuration of nwaku post 0.36.0 because we know need to be deliberate on whether nwaku nodes are running with auto or static sharding.
It also included various back and forth conversions between shards, pubsub topics, etc.
With this change, we tidy up the network configuration, and make it explicit whether it is static or auto sharded.
We also introduce the concept of routing info, which is specific to a message, and tied to the overall network configuration.
Routing info abstract pubsub topic, shard, and autosharding needs. Which should lead to easier tidy up of the pubsub concept at a later stage.
