 Description   

Currently internalQueryDisablePlanCache query knob can be only set on startup.

It was introduced in SERVER-67098.

 

However, for performance testing purposes, we would like to adjust this dynamically.

The knob is already atomic, so we just need to allow it to be changed dynamically.

We need to watch out - there may be a reason why it was startup-only initially.
