Add Nebulex instrumentation library (#83) Add instrumentation for Nebulex, a distributed cache library. This library provides solid telemetry support for this initial implementation. Caching implementation is mostly based on in-memory storage (like ETS) and RPC calls for distribution (via OTP libraries, like :erpc). AFAICT, there is not much specifics for how to translate into Semantic Attributes: those caches are not quite a DB, except maybe for the one which implements the storage; the RPC can't be reliably captured either. Given the above constraints, this initial implementation instruments the library via custom attributes (namespaced as `nebulex.*`). It's not 100% clear the behaviour of OTel for actual distributed caches - from my tests, that may create some orphan spans. I think that's fine as first release. Nebulex follow the patterns of Ecto, so this instrumentation follows a similar pattern of OpentelemetryEcto. It does include a `setup_all/1` function for convenience, that leverages the :init events Nebulex emit on process start.
