refactor product_install task for Sat5

[elyezer]

The design decision behind product_install and all *_install tasks was that every install task should return a map for installer options, then the katello_installer task grab that information and run the install command. One way to refactor is to adopt the same approach for Satellite 5 related tasks or think a different approach and make product_install handle it if doing a Satellite 5 installation.

Thanks for the explanation, @elyezer.

I'd go for separate satellite5_product_install to avoid frequent if conditions for sat5 vs. sat6

[elyezer]

👍

Then I recommend moving all the satellite5 related tasks to automation_tools/satellite5.py module, later we can refactor Satellite 6 and SAM tasks to similar modules.
