Public Dashboards: Pubdash panels get data from pubdash api (#50556)

* Public dashboard query API * Create new API on service for building metric request * Flesh out testing, implement BuildPublicDashboardMetricRequest * Test for errors and missing panels * WIP: Test for multiple datasources * Refactor tests, add supporting code for multiple datasources * Gets the panel data from the pubdash query api * Adds tests to make sure we get the correct api url from retrieving panel data * Public dashboard query API * Create new API on service for building metric request * Flesh out testing, implement BuildPublicDashboardMetricRequest * Test for errors and missing panels * WIP: Test for multiple datasources * Refactor tests, add supporting code for multiple datasources * Handle queries from multiple datasources * Replace dashboard time range with pubdash time range settings * Fix comments from review, build failure * removes changes to DataSourceWithBackend.ts regarding getting the pubdash panel query url. Going to do this in a new class, PublicDashboardDataSource.ts * Include pubdash Uid in dashboard meta * Creates new PublicDashboardDataSource.ts and adds test * Passes pubdash uid down to PanelQueryRunner.ts to a PublicDashboardDatasource can be chosen when were looking at a public dashboard * removes comment * checks for error when unmarshalling json * Only replace dashboard time settings with pubdash time settings when pubdash time settings exist * formatting and added comment Co-authored-by: Jesse Weaver <jesse.weaver@grafana.com> Co-authored-by: Jeff Levin <jeff@levinology.com>
