Reduce verbose logging for property file search

[stain]

On startup, there is quite a verbose log output from loading of property files and data sources, which can be misleading as it seems like an error:

nable to find /opt/ims/log4j.properties in local Directory
Loaded file log4j.properties using BRIDGEDB_CONFIG from /opt/ims/conf/BridgeDb/log4j.properties

Perhaps this search path for properties could be reduced, or at least prefix such logging with "DEBUG" rather than look like an error?
