Reduce the log when pacemakerd is run on command.

Hi, Andrew

I made the cluster which manages the replication of pgsql.
We are setting logpriority to "info", in order to obtain a log required for systems operation.
The log of the following whenever monitor of pgsql resource agent is performed is outputted.

Since "pacemakerd -$" is performed within pgsql resource agent, this is outputted.
Correction was created in order to hide these logs. 
If there is no problem in particular, I will want you to merge this correction.
