[C++] Managing max memory usage in Arrow

[HK Verma]

We have an application where a limited amount of memory is present for an
Arrow based Linux service. I can put resource constraints while starting
the service in Linux
<https://www.freedesktop.org/software/systemd/man/systemd.exec.html#LimitCPU=>.
However, I am wondering if it is possible, or recommended, to create  a
custom MemoryPool <https://arrow.apache.org/docs/cpp/memory.html> limiting
memory use.
Thanks,
HK
