Parallelize info intra vm

[ricab]

Introduce the parallelization of the SSH commands that are used for info within VMs with multiple cores.

With the exception of the command to fetch IPs (which follows a different scheme that is used also for list), all the necessary commands are combined into a single one and executed in one go on the instane over SSH. Two versions of this single combined command are derived: one sequential and one parallel. The parallel version is used when the VM has multiple cores. On single-core VMs, the sequential version is used.

For organization, and to avoid polluting the unnamed namespace in daemon.cpp any further, the code is now in a new helper class: RuntimeInstanceInfoHelper.

Credit goes to @andrei-toterman for the idea implemented here. Thanks!

Hey @ricab,

Could you please rebase and fix the conflicts here at your earliest convenience? I'm ready to functionally test this and get it in! Thanks!
