[Dashboard]view altered queries from dashboard

[junlincc]

Motivation / Problem to Solve

as we are slowly rolling out more native dashboard functionality, e.g. native filter select, group-by, text-based filter.... users will be able to alter queries directly from dashboard, instead of going back and forth between Explore and Dashboard.
Eventually, users should be able to add/alter, if not all, most of the WHERE clauses through dashboard control.

Proposed solution

Allow user to view altered queries from dashboard as a validation of the native dashboard actions.
