org.apache.roller.weblogger.business.DatabaseProvider
Encapsulates Roller database configuration via JDBC properties or JNDI.
To keep the logs from filling up with DB connection errors, will only attempt to connect once.

Keeps startup exception and log so we can present useful debugging information to whoever is installing Roller.

Reads configuration properties from WebloggerConfig:
```
 # Specify database configuration type of 'jndi' or 'jdbc' database.configurationType=jndi # For database configuration type 'jndi',this will be used database.jndi.name=jdbc/rollerdb # For database configuration type of 'jdbc', you MUST override these database.jdbc.driverClass= database.jdbc.connectionURL= database.jdbc.username= database.jdbc.password= 
```
