The ML autoscaling code was making an assumption that all ML nodes in Cloud will be at least 1GB. This is not correct. After allowing for logging and metrics collection it is possible for ML nodes to be smaller. This PR updates the assumption to 0.5GB.

On closer inspection the code changed quite radically in 8.3, so I think it would be best not to backport this change to 7.x. Doing so might aggravate some of the other ML autoscaling discrepancies that were fixed in 8.3. |

This change fixes a discrepancy that has existed for a long time but was revealed by elastic#91694. The ML automatic node/JVM sizing code contained a minimum node size but did not restrict the minimum JVM size to the size that would be chosen on that minimum node size. This could throw off calculations at small scale. Fixes elastic#91728
