ECOPROJECT-3416 | feat: Baremetal cost prediction

[machacekondra]

This PR add a cost estimation for baremetal self managed OCP/OVE.

The user can see the estimation when he click the cost estimation button on the overview of report page.

The calculation is based on:
https://www.redhat.com/en/resources/self-managed-openshift-subscription-guide

We predefine vCPU for calc based on vCenter VMs. We let user define the Node HW, we can pre-define it, but it's hard as each node could be different.

We also offer user to define OCP/OVE or SLA.

Example calculation:
A user has 4000vCPU on vCenter with ratio 1:4, it’s 1000cores. Bare metal node has 2sockets with 32cores. 1000cores/64cores=16 servers. We would suggest 16*1.25=20 nodes. We would calculate the price for 20 OpenShift Virtualization Engine bare metal socket-pair subscriptions.

This calculation takes into account Bare metal socket-pair subscription.
More info: https://www.redhat.com/en/resources/self-managed-openshift-subscription-guide#section-4

Current solution don't take into account core-pair subscription model. We may provide it as an option in future.
