As an API user, I can filter Test Runs by Test Run Assignee with GraphQL

Users must be able to filter Test Runs by Test Run assignee.

• Test Run assignee is set directly or indirectly using the Test Execution Assignee
• This feature should be provided as a filter of the getTestRuns query:

getTestRuns(testIssueIds: [String], testExecIssueIds: [String], testRunAssignees: [String], limit: Int!, start: Int): TestRunResults
