Nodes returned by DNS Discovery are not guaranteed to be reachable.
Hence, setting an upfront limit based on sought capability does not provide
any guarantees that such capability should be reached.
The discovery's mechanism role is to find Waku 2 nodes. As many as possible.
It is then the role of the peer manager to decide:
- whether to attempt connecting to the node based on advertised capabilities
- retain connection to the node based on actual mounted protocols.
We still want to prevent infinite loops, hence the `maxGet` parameter.
Also, there was a dichotomy between code tested, and code actually used by libp2p peer discovery, now resolved.

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.

For an edge node, there is no such thing as a "pubsub topic configuration". An edge node should be able to operate for any possible shard, and it is a per-protocol matter (eg send message with light push).
A relay node do subscribe to shards, but in this case, even metadata protocol does not need to advertise them, this is already handled by gossipsub.
Only service node should advertise their shards via metadata protocol, which is out of scope for js-waku.
