Documentation for configuring --max-old-space-size

[inqueue]

Kibana version: 4.x/5.x

Please add documentation for the best way to configure --max-old-space-size for all supported platforms. Additionally, some general guidelines for what --max-old-space-size should be would be very helpful to those who may need to configure it.

NODE_OPTIONS="--max-old-space-size=512" ./bin/kibana

Does it belong in /etc/default/kibana for platforms that support it?

Issue reference for this config is long. In no particular order:
#7103
#8795
#8103
#7217
#6862
#6727
#6153
#5764
#5170

A documented recommendation of #5170 (comment) would go a long way.

Thanks!

It's essentially an undocumented chrome v8 flag. NodeJS closed a similar issue since it outside their scope.

Just as an info, with some versions of nodejs (e.g. v4.4.7) the option is called --max_old_space_size (with underscores instead of dashes).
