Remove obsolete cve_scanner package

[mpreisler]

CVE scanning is now done as a task, the cve_scanner package is of no use. Let's remove it so that we don't have to maintain it any more.

[jan-cerny]

I don't think we can remove it, because oscapd-cli scan uses cli_scan which uses CVEScanListAsync which uses Worker which is defined in cve_scanner package.
@dahaic @mpreisler @matejak @yuumasato @Mildass @matusmarhefka Do we want to drop this functionality from oscapd-cli?

[matusmarhefka]

@jan-cerny Is atomic scan using oscapd-cli in any way? I think it uses oscapd-evaluate.

[dahaic]

@matusmarhefka atomic scan is just using daemon. Let's look at this problem from the perspective of daemon, not of one particular use case.

@jan-cerny I would suggest to preserve the functionality.

[jan-cerny]

@matusmarhefka I think it isn't using oscapd-cli. I think you're right that it uses oscapd-evaluate.

[jan-cerny]

@dahaic I agree that we should preserve the functionality.

[jan-cerny]

Do you think we should rework the code to avoid using the cve_scanner package?

[mpreisler]

the cli_scan stuff is virtually unused, it was replaced with oscapd-evaluate and the task API VulnerabilityScan mode. We can remove cli_scan IMO, it's obsolete anyway.
