Add parameter for Apache LogLevel in error logfile

Add the log_level parameter to control LogLevel for Apache vhost.
By default, Apache only logs warnings and errors in its errors logfile,
while request timeouts are logged by mod_reqtimeout at LogLevel info.
Default error_log_level value is not defined, which corresponds to
the default Apache's LogLevel warn.
