sysutils/p5-OpenTelemetry: Add new port

The OpenTelemetry distribution is the Perl implementation of
OpenTelemetry. This module provides an entrypoint and exposes exposes
an interface to get  and set components that need to be globally
available.

The OpenTelemetry standard keeps a strict separation between an API
layer that implements an interface that is backend-agnostic, and an SDK
layer that can be connected to the API to do the actual work.

    $logger_provider = OpenTelemetry->logger_provider;
    OpenTelemetry->logger_provider = $new_logger_provider;
