feat: Eigenda Config

[gianbelinche]

What ❔

This PR adds some new configs necessary now that the proxy is not going to be used anymore.
We may need more or less fields in the future, this is just to get ahead.
Some configs like api_node_url will need to be removed once we remove the eigenda proxy, but for now to preserve functionality until rust proxy is finished I just left comments were removal would be necessary.
There are two variants:

da_client:
  eigen_da:
    memstore:
      api_node_url: http://127.0.0.1:4242 # TODO: This should be removed
      max_blob_size_bytes: 2097152
      blob_expiration: 100000
      get_latency: 100
      put_latency: 100

da_client:
  eigen_da:
    disperser:
      api_node_url: http://127.0.0.1:4242 # TODO: This should be removed
      disperser_rpc: <your_desired_disperser>
      eth_confirmation_depth: -1
      eigenda_eth_rpc: <your_desired_rpc>
      eigenda_svc_manager_addr: '0xD4A7E1Bd8015057293f0D0A557088c286942e84b'

Looks Ok, but would take comment into account, an incorrect parsing in the config (due to a typo for example) might be a headache later on if we don't catch it as soon as possible.

loading a config, but not matching to any da_config should result in an Error.

[gianbelinche]

I don't think it should be an error, if you are using avail for example, you don't want the proxy layer to be added, this takes care of that.
You cannot add it, since it would later need the specific config for eigenda, which it would not have
