feat: add flag to disable persistent dashboard state

[AdityaHegde]

We have 2 ways of persistent dashboard state,

1. All dashboard state is save per tab. Going back to dashboard without url params will reset to the full dashboard state.
2. Certain dashboard states are saved. A revisit to this dashboard will restore this subset.

Adding a project level feature flag disable_persistent_dashboard_state to disable both of these.
