Move log_autovacuum_min_duration into its correct sections 

This GUC has already been classified as LOGGING_WHAT, but its location
in postgresql.conf.sample and the documentation did not reflect that, so
fix those inconsistencies.

Causes each action executed by autovacuum to be logged if it ran for at
least the specified amount of time. Setting this to zero logs
all autovacuum actions. <literal>-1</literal> (the default) disables
logging autovacuum actions.
If this value is specified without units, it is taken as milliseconds.
For example, if you set this to
<literal>250ms</literal> then all automatic vacuums and analyzes that run
250ms or longer will be logged. In addition, when this parameter is
set to any value other than <literal>-1</literal>, a message will be
logged if an autovacuum action is skipped due to a conflicting lock or a
concurrently dropped relation. Enabling this parameter can be helpful
in tracking autovacuum activity. This parameter can only be set in
the <filename>postgresql.conf</filename> file or on the server command line;
but the setting can be overridden for individual tables by
changing table storage parameters.
