Identify secure jobs in a pipeline

What does this MR do?

A Security::JobsFinder has been added to return builds/jobs for a pipeline that are related to the Secure team products. These include SAST, DAST, Dependency Scanning and Container Scanning.

This issue resolves the part of #13662 (closed) regarding finding Secure jobs in a pipeline.

Technical choices

• We can only determine Secure jobs at the moment by their artifacts:reports:{sast | dast | ...} in the Ci::Build#options
• There is a feature toggle, :ci_build_metadata_config, that if turned on would cause the options to be stored in Ci::BuildMetadata#config_options. This MR ensures Secure jobs are found independently of the feature being enabled or disabled.
• When querying, the DB will choose one of the commit_id indexes as we're also searching for pipeline.
