Refactor vulns and vuln events tables

[Hubtrick-Git]

Vulnerability table changes

• Migrate the id columns of the 3 vuln tables dependency_vulns, first_party_vulnerabilities and license_risk.
• Previously the id was a 256 bit hash stored as a text -> Now its only a 128 bit hash stored as a uuid
• This leads to 1/4 of the disk space required and performance improvements regarding internal processing of UUIDs in comparison to text

VulnEvent table changes

• Drop updated_at column to reduce space
• Use 3 foreign key columns, 1 for each vuln instead of the current single column

Now we need to refactor the existing code regarding the affected columns

Queries

• Change all queries using vuln_events
• Change all queries using vuln_ids

Go Code

• Change vuln event model and refactor affected code
• Change the vulnerability model and refactor affected code
