Configuring HUB_MAX_MEMORY setting

The configuration parameter HUB_MAX_MEMORY is automatically set for relevant containers in Kubernetes-based deployments. The value is computed as a percentage of the memory limit, with 90% being the default.

In the gen04 deployment sizings, the maxRamPercentage controls the percentage used; the values for this setting were chosen so that HUB_MAX_MEMORY has the same values as before.
