In this PR, we aim to add a data layer connection in the HttpClient and read the data_layer configuration from chia-config.

Thanks for the PR. I see there is the details in here for getting the http client for datalayer, etc, but no actual datalayer endpoints. Are you planning to add anything RPC calls to datalayer in this PR? (Farmer, for example: https://github.com/Chia-Network/go-chia-libs/blob/main/pkg/rpc/farmer.go)

In response, I'd like to clarify that in this PR, I didn't intend to implement any actual RPC calls. However, I realize that I overlooked the inclusion of the DataLayerService in client.go.

Looks good overall. One minor (but important) change and I think we can merge
