Let the developer configure desired logging with system properties

Now by default, Wildfly logs at ERROR level in the CONSOLE and DEBUG level in
the project.build.directory/test.log file.

For this to happen, we need to copy a the /src/test/wildfly-resources file (filtered)
to the Wildfly standalone configuration directory during the process-test-classes phase.

Example:
mvn verify -Dwildfly.logging.console.level=DEBUG

Also:
* removed useless <id>Memory-backend</id> profile definition (it is the default)
* removed redundant info in Cassandra-backend profile

Add debug logging (will be useful for tracking issue #57)
Fix InfluxTest: '30sec' is not a valid duration format

'30s' is a valid one.

The RestHandler was thus looking for metrics since epoch.
Not a big deal with this test case, as we expect the backend
to select all the metrics anyway.

Log Rest Test messages at DEBUG level in the console
ptrans: added "new config-file" parameter
ptrans logging: use bundled log4j.xml in production, log4j-dev.xml in development

Bundled log4j.xml outputs everything to stdout, at INFO level

Users who want to customize logging may specifiy a path
to a log4j configuration file with the 'log4j.configuration'
system property
