Allow the bulk updating of Issues using GraphQL API
Summary
Allow bulk updating of issues using the GraphQL API.
There is an updateIssue mutation to update an issue but none to update a collection of issues at once. You can bulk update: status, assignees, epic, milestone, iteration, labels, health status, subscription individually.
Recreating the issue list in Vue/GraphQL requires the ability to bulk update several attributes on multiple issues. For performance reasons this can have a sensible limit.
