This PR is the first stage of bring back the data plane to the SRF runtime. This adds the following to the `data_plane` namespace: - `Callbacks` - a struct of static methods used to handle UCX callback on locally initiated UCX transactions, e.g. issuing a tagged send or and RDMA GET. - `Request` - a struct which holds the state of an async transaction. This object holds a bit more data than just a promise/future pair. I figure the API will have two ways to kick off an async transaction, one that takes a ref to a `Request` and another that return a `Request`. The latter requires a heap allocation, so the former could be used as a subtle optimization for structured concurrency. - `DataPlaneServerWorker` which is the Runnable that drives the UCX worker's progress method which ultimately executes the UCX callbacks. More functionality will be added to this component over time, specifically using `ucp_nb_probe` to match any incoming events who's payloads were larger than the pre-posted buffers. The remaining work in this PR is moving the ucx tests into the internal tests binary and re-enables the RDMA get test. This is not a complete implementation of the UCX Data Plane. #144 was created to address the WIP state.
