Describe the issue:
Need to clearly document resource requirements in Table 7.1. [1] is also applied to during rolling upgrade.
While rolling upgrade is in progress, one node gets rebooted at a time, so other 2 nodes needs have
required resources.

Eg: 72 GiB memory for bases services for a 3 node cluster, during rolling upgrade 2 nodes need to have 72 GiB, 36 GiB each.

It's highly appreciated if we document those requirements in Table 7.1 [1] needed from 2 nodes for rolling upgrade.

Similar document bug [2] has raised by same customer but they're still pushing us to clearly document requirements for rolling upgrade.
They need to see a note including " .... for rolling upgrade."
