fix: increase emqx_router_sup restart intensity 

The goal is to tolerate occasional crashes that can happen under relatively normal conditions
and don't seem critical to shutdown the whole app (emqx).
For example, mria write/delete call delegated from a replicant to a core node may fail,
if the core node is being stopped / restarted / not ready.

Increase `emqx_router_sup` restart intensity.
The goal is to tolerate occasional crashes that can happen under relatively normal conditions
and don't seem critical to shutdown the whole app (emqx).
For example, mria write/delete call delegated from a replicant to a core node by `emqx_router_helper` may fail,
if the core node is being stopped / restarted / not ready.
