Respecting default rolling_enabled in plugins. (#7275)

Some plugins indiscriminately enable log rolling without consideration
of the system value. This looks like it is just a mistake that went
unnoticed because we've always had this enabled. This patch changes a
couple plugins to respect the proxy.config.log.rolling_enabled value by
not overwriting it with TSTextLogObjectRollingEnabledSet unless
explicitly configured to do so.
