Add a new workflow to test that updater works as expected (#10599)

* Add workflow for installing latest version of netdata, building from source of this branch & running the updater. Add script build-dist to create the artifacts used for the update.

* Add more distributions, arguments in updater script & accomodate review comment

* Run updater within docker for 6 distributions

* Remove unecessary change in updater

* Correct netdata_version --> updater_version in check-updater script

* Review comments: remove unused vars & replace == with =
