There are currently two workspaces endpoints:

/organizations/<id>/workspaces is required to filter workspaces by the organization.
/users/<id>/workspaces returns all workspaces a user can access, across all organizations they have access to.

These can be combined into /workspaces. This endpoint should be paginated, always return all workspaces the authenticated user has access to by default, and have query parameters to filter the response.

Pagination can follow existing patterns found in the codebase. Here are some query parameters I can immediately see being valuable:

• owner - Return all workspaces that are owned by a user with the specified name.
• organization - Return all workspaces in the specified organization.
• latest_job_status - Returns all workspaces with the latest build having the job status provided. This will be used to query: "all workspaces with the latest status of failed".
• updated - Returns all workspaces that are up-to-date or not.
• template - Returns all workspaces using the specified template name.
• version - Returns all workspaces using the specified version name.

Inspiration for this is drawn from making the workspaces page.
