automated postrelease testing (#1460)

* wip postrelease testing

* fix replicated CLI install

* f

* fix bin download

* disable CI again

* needs get-tag

* test reset+reinstall with actual build, not previous k0s

* add previous-stable upgrade tests, build 'previous-k0s' app version

* that's silly

* f

* fix previous-stable test

* reenable CI

* disable almost all of CI again

* pass the post-upgrade target ec version to the check instead of expecting a static suffix

* add new param in CI as well

* reenable CI

* fix previous version upgrade onrelease test

* fix upgrade version specifier

* include upgrade version specifier in docker tests
