Changes:

Feature: Now runtime application metrics can be reported directly from python, by using the "report_app_metrics" function on cb_common.py (on scripts common). This is now used by the Hadoop VApp (cb_hadoop_report.py)
Feature: The command "monlist" now lists the current experiment id and the number of samples for this experiment.
Feature: Now all VApp types also support "load_profiles". This parameter is automatically submitted to the load generator during execution.
Feature: In the first time "monextract all" is executed after a --hard_reset, the log files are also included alongside the generated csv files.
Feature: If an experiment was executed by reaging command from trace file (option --trace), this file is also included alongside the generated files created by "monextract".

Bugfix: Redis startup on VMs with redis-server vesion 2.4.X now works properly.
Bugfix: NTP service startup works on both RedHat and Ubuntu VMs.
Bugfix: Configure was incorrectly considering "netcat" utility absent when executed on RHEL nodes.
Bugfix: Executing CB as root on RHEL resulted in failure while extracting CSV files.
Bugfix: vmcdetach all was failing while trying to restart the HOST runtime OS metrics collector.
Bugfix: The "scalable" execution mode is now fixed. In this execution mode, both the load_generator and load_manager send their logs to the "metric aggregator" VM.

Code Maintenance: General improvements for the cbplotgen.R utility.
Code Maintenance: Now all files produced by monextract use relative time. The beginning of the experiment is marked as the first moment when a command was detected in the trace file (this will make running multiple experiments in the same file impossible for now - will fix it later).
