Multiple changes for June release

- Change inittest in warmuptest. This has now a warmuptime, warmupspeed,
packet size and flow size.
- Change in centos.json. This will now also copy deploycentostools.sh
during image building so that it can be used to re-compile prox in the VM
by typing "./deploycentostools.sh compile"
- runrapid.py parameters needing a file name, need to be complete file
names: no extensions will be added any more by the scripts.
- Changes in createrapid.py to handel the openstack CLI output in a
simpler way.
- The management interface of the VMs can now also be an SRIOV interface.
We have now an extra optional parameter in the VM sections of the
rapiVMs.vms file: SRIOV_mgmt_port
- Changed the name of some sections and keys in the environment file since
runrapid.py will not always communicate to OpenStack VMs. This could be
containers or any other (virtual) machine.
- The previous MachineMap.cfg has been renamed to machine.map
- A new test has been added: monitorswap is just showing the statistics of
a swap (virtual) machine, without generating any packets. This is useful
in situations where an external tester is used.
- Latency and core statistics can now be measured even if there are
multiple PROX cores and tasks running. A new parameter has been added in
the test files with following default value: tasks=[0]. During the
collection of statistics, all tasks in this list will be queried. It is
ok to have a non-existing task in such a query since it will be ignored.
- A --screenlog parameter was added for runrapid.py allowing for more
detailed output on the screen during debugging. No need to check the log
file.
- Previous tests to run multiple packet size with a given flow size and to
run multiple flow size, with a given packet size are now combined by
specifiying 2 lists: packetsizes & flows
- The screen output of this test has also been reworked with more
meaningful column names and the test result is now in the field "core
received". This allows also for faster termination of the test: When the
all packets sent by Gen NIC are received by the cores within the
thresholds for packet loss and latency, the test is now stopped, even we
were requesting more packets to be sent.
