Make the scanning of a file/URL less cumbersome

[plusvic]

When the only thing you want is to upload a file/url and get the verdicts back, the existing method is a bit cumbersome. The vt scan command returns an analysis ID that then you need to use with vt analysis in order to get the analysis results. And you may need to call vt analysis multiple times until the analysis is completed.

It would be great if this process can be simplified.
