Draft: investigate missing fields **DO NOT MERGE THIS**

What does this MR do and why?

This MR is simply a SPIKE. We're investigating the missing fields in GraphQL in order to request them from the backend.

Mock GrahpQL Server

https://gitlab.com/dpisek/vulnerability-graphql-mock

Result of spike

• backend Add the following fields:

# Enums
enum VulnerabilitySupportingMessageName {
  RECORDED
}
# Types
type VulnerabilityRequestResponseHeader {
  name: String
  value: String
}

type VulnerabilityRequest {
  body: String
  method: String
  url: String
  headers: [VulnerabilityRequestResponseHeader!]
}

type VulnerabilityResponse {
  body: String
  statusCode: String
  reasonPhrase: String
  headers: [VulnerabilityRequestResponseHeader!]
}

type VulnerabilitySupportingMessage {
  name: VulnerabilitySupportingMessageName
  response: VulnerabilityResponse
}

type VulnerabilityEvidenceSource {
  name: String
}

type VulnerabilityAsset {
  name: String
  url: String
}

type VulnerabilityRemediation {
  diff: [String!]
}

• frontend Migrate ee/app/assets/javascripts/vue_shared/security_reports/components/merge_request_note.vue and ee/vue_shared/security_reports/components/event_item.vue to use camelCase fields.
• frontend Find vulnerability.hasMr occurrences. We won't have this field anymore, instead use the mergeRequest field to deduct this information.
• frontend Find mergeRequestFeedback occurrences and rename them with mergeRequest
