[jira] [Created] (ARROW-15408) [C++] Environment variable to turn on memory allocation logging

Will Jones created ARROW-15408:
----------------------------------

             Summary: [C++] Environment variable to turn on memory allocation logging
                 Key: ARROW-15408
                 URL: https://issues.apache.org/jira/browse/ARROW-15408
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
    Affects Versions: 6.0.1
            Reporter: Will Jones
             Fix For: 8.0.0


In Python, there is a [{{log_memory_allocations}} function|https://github.com/wesm/arrow/blob/33111644be84f84ce4601889fee06c6d17f05279/python/pyarrow/memory.pxi#L63] to change to use the LoggingMemoryPool. It would be nice to be able to do this in C++ and one very convenient way would be through an environment variable, since we already support {{ARROW_DEFAULT_MEMORY_POOL}}. Should probably be named something like {{ARROW_LOG_MEMORY_ALLOCATIONS}}.
