Feature: Add automatic setup of QE binaries

[t-reents]

@giovannipizzi @mbercx @Minotakm Quickly summarizing what we discussed last week:

It would be nice to have a cli command that takes care of setting up all the QE binaries that are typically used, e.g. pw.x,
ph.x, etc. This would simplify the setup of different environments, and in general the setup process for new users.

Two options should be supported:

• Given a prepend text (e.g. which modules to load), simply use which pw.x on the computer to identify the binaries and setup the codes accordingly (this is especially useful for new users that don't have multiple compilations of QE)
• Provide a specific directory of the binaries and iterate through them (or a predefined list) to setup the codes. This would also be interesting for more experienced users

In addition to the automatic setup, it would be also nice to add a cli command to test the setup of the QE codes. For a tested and very simple system, e.g. Si, submit a calculation to the computer and return whether the calculation was successful. This could probably run in the background.

More details can be discussed when having a first draft. I'd be happy to take care of this when we block some time for the QE plugin.
