Calculate deserved slots only based on active i.e. non-idle consumers in e.g. Symphony HostFactory symA requestor

This comes from discussion in TS009907566 "Hostfactory scale up while cluster had free slots".

"egosh consumer view" provides, in addition to other outputs, "Planned Quota" and "Share Quota", for a particular resource group (RG): "Planned Quota" is a static number calculated based on resource plan settings such as share ratio, slot limit, etc (assuming we use share model) for all consumers, while "Share Quota" is the actual slots a consumer gets allocated.

Symphony has the concept of deserved slots of a consumer, used in many places, such as HostFactory when calculating for symA requester, PMC Dashboard (GUI), and SMC (Symphony Multi Cluster) ... We find -A) deserved slots equals "Planned Quota", when allocated slots <= Planned Quota -B) deserved slots equals allocated slots when allocated slots > Planed Quota.

We find the above way of calculating deserved slots is not reasonable. We request that the deserved slots be calculated purely based on the active (i.e. non-idle) consumers. Although we think this change should be made for other Symphony areas such as PMC, SMC, this request is only about HostFactory - changes to non HostFactory areas are not required, though desired.

The issue was discussed in TS009907566 and related email exchanges with IBM Support. Our use case is: a cloud cluster has different root consumers, but only 2 leaf consumers under one root consumer are really used and active, other leaf consumers under the same parent and other root consumers are all idle, thus "Planned Quota" is very low for the two active consumers. When these two consumers have low demands themselves, A) is used and thus the deserved slots become very low, causing symA to provision slots while there are lots of free slots available.

    I checked around. We do not really use slot limit, so the solution can be based on the assumption that no slot limit is used.

    For compute, we do use share model only, but on-prem uses quite a lot of slot limit. For cloud where HostFactory in use (which I care mainly here), I believe we don't use slot limit yet but I'll need to confirm within the team and get back

    Peter, for your case, can we assume the resource plan will use a pure-sharing model and not set limits on sharing, basically, the all the slots in the resource group are allocable to these two leaf consumer nodes?
