Filter memory per vcpus

[mhuguesaws]

It will be nice to have the ability to filter instance providing an amount of memory per vCPUs considering that all vCPUs will be utilized.

You are able to query a ratio of memory to vcpus but not a specific memory quantity per vcpu. Does that take care of your use-case or are you looking for the latter?

      --vcpus-to-memory-ratio string                   The ratio of vcpus to GiBs of memory. (Example: 1:2)
