Mount command line is logged at inappropriate log level in RHEL 6

Issue

• rgmanger, misleading mount cmd in syslog
• When a service does mount a filesystem the mount command itself is logged with a severity of "err". This may confuse some monitoring. Please compare example below.

2013-03-11T16:11:15.011719+01:00,aeptst001,rgmanager[14016]:,local4,err, [fs] mount -t ext4  /dev/mapper/VGmysqldb1-LVmysqldb /opt/MYSQLDB1

• Customer is using a straightforward cluster.conf, using default log settings. They noticed that mounts of filesystems are logged at LOG_ERR priority.
• As this is a normal cluster operation, they are expecting this to be logged at a lesser priority (e.g. rgmanager's default of LOG_INFO).
• Please backport https://github.com/ClusterLabs/resource-agents/pull/220
