At this moment relu_layer op doesn't allow threshold configuration, and legacy RELU op allows that.
We should add configuration option to relu_layer.

This will be a breaking change so needs to be done with a major release.

Currently OperationDetail and OperationField are inner classes within OperationServiceV2. These should be in their own outer classes for ease of serialisation and consistency.

Our docs currently requires an Impala instance to be built. At least in the last tutorials (the first 3 were written recently and don't use it), and in the Impala docs.

It's not ideal to require Impala running for the docs. There are two things we can do to avoid this:

• For generic (all backends) docs, we can simply use the SQLite backend, which doesn't require anything, not even dependencies

Currently, all results are typed as BIGINT. Given the constrained range for each of the field types, we can derive tighter type bounds.
