Enable Scheduling of Workspace in Ad Hoc Analysis

[#1]

Currently Ad Hoc Analysis enables scheduling only one report in a workspace at a time. If we have multiple reports in a workspace, we cannot schedule all reports to be delivered in excel format in multiple tabs. Large analysis projects require multiple reports/multiple workspaces. The ability to schedule the entire workspace and email the report in an excel format will improve the end to end experience of Ad Hoc Analysis significantly.
