SDK spends an unreasonable amount of time in restoring out-of-support SDKs

This command took more 2-3 minutes depending on the network connection. As far as I can tell, these downloads run in serial. I'm not sure why we need to download and restore out-of-support SDKs (1.0, 2.1, 2.2.x, 3.1.0, 5.0, 7.0)?

These are the runtimes and we have tests that target those. We could potentially change the logic to only restore these when we expect to run tests. We do it on the primary machine so that the stage 2 sdk gets updated with these runtimes and copied to the test machine all at once.

[ViktorHofer]

Right, but why are we restoring 1.0.5 and 1.1.2? I hope we don't run our tests against those runtimes which have been out of support for nearly 10 years now.
