Indicate restart required for additional props

Update the generated server-properties.md to indicate that some
additional properties require restart to take effect. The generated
documentation for these were fixed after 2.1.3 was released, so this
change is to update the docs from the 2.1.4-SNAPSHOT build after
apache/accumulo#4780 was merged.

This fixes #438
