Allow for creating a Jira ticket from Quality-time

[Sebastiaan127001]

User story

As a quality manager I want to create an issue in the configured issue tracker and have it automatically linked from Quality-time so that I can create and link issues in one step.

Acceptance criteria

The story is considered complete if:

• The user can create an issue for a metric in the configured issue tracker from Quality-time, and
• The issue is linked from the metric, and
• The metric is linked from the issue

Assumptions

• An issue tracker is configured.
• The configured issue tracker user has the necessary rights to create an issue in the issue tracker.
• If the Quality-time user is a different user than is configured for the issue tracker, the Quality-time user can still edit the newly created issue in the issue tracker.

Out of scope

• Quality-time doesn't decide on its own to create tickets.
• Automatically accept the metric as technical debt (if red or yellow)
• Automatically getting the available project keys and issue types from Jira.

Tasks

Components

Frontend

• Add a field for a default project for new issues to the issue tracker configuration
• Add a field for a default issue type for new issues to the issue tracker configuration
• Add a button next to the issue tracker id field "Create new issue for this metric"
• Button should be inactive if there's no issue tracker configured.
  • Button should be inactive if the user removes the issue tracker.
• Clicking the button invokes the external server endpoint for creating issues.
• The frontend uses the issue id returned by the external server to open a new browser tab for the user to change the issue with extra information.
• If the configured issue tracker user has no rights to create issues in the issue tracker or something else goes wrong, show an appropriate error message using the toaster.

External server

• Add endpoint to create an issue for a specific metric. The endpoint uses the issue tracker (e.g. Jira) API to create a new issue (with the metric name as title), inserts the issue id into the issue id field, and returns the issue id to the frontend.

Feature tests

• User tries to create a new issue (really creating an issue would require a fake issue tracker)

Documentation

• Update changelog
• Add instruction to user manual
  • Mention that new tab may be blocked by the browser and user needs to allow Quality-time to open a new tab.
• Update screenshots
