Make monitor trigger autodownload of result when a new repo is scanned

This introduces a new `autoDownloadVariantAnalysisResult` command which
will be called by the VariantAnalysisMonitor every time it detects a new
repo has been scanned.

In turn, this will use the `autoDownloadVariantAnalysisResult` method
which we defined in an earlier commit on the VariantAnalysisManager.
