Non thread safe version of opentelemetry-cpp

[luxapana]

We need to use opentelemetry-cpp in an application which require very low latency message processing. The application is architected in way to create thread zones where each zone is associated with a single thread. All code that belong to a thread zone are written in un-thread safe manner. So most of the classes are not thread safe as they need not be. This is done to increase performance by reducing locking (even atomics). Due to same reason we dont use shared_pointers.

What are my options to use opentelemetry-cpp in this setting?
