Jira Integration - create issue in Jira using API

Why are we doing this work

Currently our MVC for Jira integration for Vulnerabilities is using special link generated in Jira that allows to create issue easily. However this method is no longer officially supported. We need to switch to use Jira REST API instead. The flow for the users will be very similar: users will click on button on Single Vulnerability page to create issue in Jira, then we will do the call to our API to start issue creation. When everything is ok and the issue is created, we are storing the internal link between Jira issue and Vulnerability and present that information for users. In case of failure we are responding with error message.

Implementation plan

• backend create service that creates issue in Jira internally, extend JiraService with method to create issue in Jira (https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issues/#api-rest-api-3-issue-post) and create link between Vulnerability and Jira Issue using Vulnerabilities::ExternalLink (#276897 (closed))
• backend create mutation in GraphQL to create issue from Vulnerability,
  • backend catch all errors from Jira and return them in the mutation response
• backend modify ee/app/finders/projects/integrations/jira/issues_finder.rb to return issues related to vulnerability based on the created link
