SERVER-85789 Update server parameter docs
Persistent query settings (PM-412) use cluster server parameters
internally. In SERVER-78801, we added checks prohibiting running
concurrent cluster server parameter updates. The intention of this
change is to reflect these checks in the available technical
documentation. Additional changes result from updating to the most
recent state of the code, adding details, formatting,
restructuring, and running a spell checker.
