Better way to set max-old-space-size

[PSiAU]

As far as I know, the only place to set max-old-space-size is via NODE_OPTIONS in /opt/kibana/bin/kibana. This is on Debian with kibana installed via the package.
This file gets overwritten during a version upgrade which necessitates updating the file manually each time.
Surely there must be a better way to set max-old-space-size without it getting overwritten after every upgrade?

Given that we really want node to be an implementation detail rather and we recommend that this be set, I think this does need to be configurable somehow via kibana itself.

Btw, I recently filled #7237 and I think they both address the same problem from different angles.

Please do not add another parameter, but use the standard OS tools (as I suggested in the other issue)

Closing, this can now be done with a node.options file in the configuration directory.
