look into reducing fixed properties #5696
Description
Is your feature request related to a problem? Please describe.
A fixed property is one that requires restart of the related servers for a change to take effect. This is unavoidable in some cases depending on the property. However, when working on #5632 I saw several places where a fixed property could be made non-fixed.
Describe the solution you'd like
Look into all FIXED_PROPERTIES in Property and make as many non-fixed as we can.
