FELIX-1180 Improve Karaf DefaultJDBCLock to use proper logging mechanism instead of System err prints.
- Added bootstrap logger using java.util.logging
- Log file will be the default "out" file appender from log4j config
- File location can be overridden by setting "karaf.bootstrap.log" in config.properties
- There are probably better ways to do this, but this works reasonably well and gives a common logging interface (juli) to work with.
