Description of problem:

Running foreman-maintain upgrade check --target-version x.y.z will trigger the internal execution of the same verification multiple times even if nothing that would change the results was executed between the runs.

How reproducible: 

Always

Is this issue a regression from an earlier version:

no

Steps to Reproduce:

1. Run an upgrade check an observe how many times the task "Checking repositories enabled on the system" is executed

Actual behavior:

Tasks "Checking repositories enabled on the system" and "Checking for presence of upstream repositories" do exactly the same thing. Adding those two tasks, we do have 3 executions of "dnf repolist enabled -d 6 -e 0" which will bring the same results.

Expected behavior:
Ideally, it would be executed once and the information cached.
