Version 1.15.0

This release targets the OpenTelemetry SDK 1.15.0.

Consistent sampling

• ConsistentSampler does not unset p from tracestate when deciding not to sample (#350)
• Add consistent reservoir sampling span processor (#352)

Micrometer MeterProvider - New 🌟

This utility provides an implementation of MeterProvider which wraps a Micrometer MeterRegistry and delegates the reporting of all metrics through Micrometer. This enables projects which already rely on Micrometer and cannot currently migrate to OpenTelemetry Metrics to be able to report on metrics that are reported through the OpenTelemetry Metrics API.

Runtime attach

• Do not attach if not requested from the main method on the main thread (#354)
• Fix "URI is not hierarchical" during runtime attachment (#359)
