TEST-#2598: Add test for clean install from source (#2599)

* TEST-#2598: Add test for clean install from source

* Resolves #2598

This change adds a test for installing Modin without all of the testing
dependencies.

It is intended to test how a user who does not have all of the test
dependencies will see a Modin import.

* TEST-#2598: Target Python3
