Merge pull request #113 from nachoBonafonte/Update-to-Opentelemetry-spec-1-0-1
Update to opentelemetry spec 1.0.1, including: * Swiftify Status struct, converting it to an enum and associated description only for error status * Renamed TraceConfig to SpanLimits, and moved Sampler out to TracerSharedState * Renamed Probability sampler to TraceIdRatioBased * Allow usage of ParentBased sampler (it was not possible to create it before from a user perspective) * Update OTLP protocol to 0.7.0 * Update grpc-swift to 1.0.0 and generate swift-proto files with this version ( Fixes #96) * Rename IdsGenerator protocol to IdGenerator
