Description

This PR uses --output flag for save JSON reports, instead of output redirection to a file. So we don't need sync command anymore (it was added #2191).

Also it adds a log keeping on scanning pods: Trivy prints logs in stderr, so we can redirect this output into a file:

... 2>/tmp/scan/%s.log
