Feat/implement findcpes cpe search

[melbiialy]

Summary

Implements findCpes in the CveSearch Thrift service to search CPEs by vendor, product and version.

Changes

• Thrift API: Implement findCpes(1: string vendor, 2: string product, 3: string version) in CveSearchService in cvesearch.thrift with Javadoc.
• Implementation: Implement findCpes in CveSearchHandler that:
  • Calls CveSearchWrapper.search(vendor, product) to query the CVE Search API and obtain List<CveSearchData>.
  • Extracts CPE strings from CveSearchData.getVulnerable_configuration() (map keys).
  • Filters by version when provided; empty or "*" version returns all CPEs.
  • Parses CPE 2.3 format via getVersionFromCpe() (version at index 5).
• Input handling:
  • Null or empty vendor/product returns an empty set.
  • Null version returns an empty set.
  • Trims vendor, product, and version; normalizes version to lowercase.
• Error handling: Wraps IOException from the CVE Search API in TException with cause.
• Documentation: Add Javadoc for findCpes and getVersionFromCpe, and Thrift docstring for the method.

Example usage

• findCpes("apache", "httpd", "2.4") → Set of CPEs like cpe:2.3:a:apache:httpd:2.4:...
• findCpes("apache", "httpd", "*") → Set of all Apache httpd CPEs
• findCpes("apache", "httpd", "") → Set of all Apache httpd CPEs
