The OpenSSL library provides a way to replace the default allocator with
user supplied allocator (malloc, realloc, and free).
Create a memory context specifically for OpenSSL to allow tracking the
memory usage that has originated from within OpenSSL. This will provide
a separate memory context for OpenSSL to track the allocations and when
shutting down the application it will check that all OpenSSL allocations
were returned to the allocator.
