Introducing collection of all fuel and stack deployment logs.

The purpose of this patch is to collect all available Fuel snapshots- and
stack/node ldeployment logs for later off-line troubleshooting.
The intention is that Jenkins, or other deployment robots will be able to
collect all logs from the deployment and store it at some repository where
developers can fetch it and perform off-line post deployment trouble-shooting.
Following script arguments have been added:

CI Arg changes:
Added an argument to ci/deploy.sh:
-L [Deploy log path and file name], E.g.
   -L ~/jenkins/deploy/deploy-888.log.tar.gz
   This will create an tar gzip archive at the path and filename pointed out.
   If -L is not specified, the log archive will be placed under the CI directory
   with the following name convention: deploy-YYMMDD-HHMMSS.log.tar.gz

Fuel Internal deploy changes:
Added an argument to ci/deploy.py
-log [Deploy log path and file name], E.g.
     -log ~/jenkins/deploy/deploy-888.log.tar.gz
     This will create an tar gzip archive at the path and filename pointed out.
     If -log is not specified, the log archive will be placed under the CI
     directory with the following name convention:
     deploy-YYMMDD-HHMMSS.log.tar.gz

READY TO MERGE!
VERIFIED!

 * EXAMPLES:
 
 - Install Fuel Master and deploy OPNFV Cloud from scratch on Hardware Environment:
 
-    sudo python deploy.py -iso ~/ISO/opnfv.iso -dea ~/CONF/hardware/dea.yaml -dha ~/CONF/hardware/dha.yaml -s /mnt/images -b pxebr
+    sudo python deploy.py -iso ~/ISO/opnfv.iso -dea ~/CONF/hardware/dea.yaml -dha ~/CONF/hardware/dha.yaml -s /mnt/images -b pxebr -log ~/Deployment-888.log.tar.gz
 
 
 - Install Fuel Master and deploy OPNFV Cloud from scratch on Virtual Environment:
 
-    sudo python deploy.py -iso ~/ISO/opnfv.iso -dea ~/CONF/virtual/dea.yaml -dha ~/CONF/virtual/dha.yaml -s /mnt/images
+    sudo python deploy.py -iso ~/ISO/opnfv.iso -dea ~/CONF/virtual/dea.yaml -dha ~/CONF/virtual/dha.yaml -s /mnt/images -log ~/Deployment-888.log.tar.gz
 
 
 - Deploy OPNFV Cloud on an already active Environment where Fuel Master VM is running so no need to install Fuel again:
 
-    sudo python deploy.py -nf -dea ~/CONF/virtual/dea.yaml -dha ~/CONF/virtual/dha.yaml
+    sudo python deploy.py -nf -dea ~/CONF/virtual/dea.yaml -dha ~/CONF/virtual/dha.yaml -log ~/Deployment-888.log.tar.gz
 
     => with plugin installation
-    sudo python deploy.py -nf -dea ~/CONF/virtual/dea.yaml -dha ~/CONF/virtual/dha.yaml
+    sudo python deploy.py -nf -dea ~/CONF/virtual/dea.yaml -dha ~/CONF/virtual/dha.yaml -log ~/Deployment-888.log.tar.gz
 
     => with cleanup after deployment is finished
-    sudo python deploy.py -nf -dea ~/CONF/virtual/dea.yaml -dha ~/CONF/virtual/dha.yaml -c
+    sudo python deploy.py -nf -dea ~/CONF/virtual/dea.yaml -dha ~/CONF/virtual/dha.yaml -c -log ~/Deployment-888.log.tar.gz
 
     => no healthcheck after deployment is completed
-    sudo python deploy.py -nf -dea ~/CONF/virtual/dea.yaml -dha ~/CONF/virtual/dha.yaml -nh
+    sudo python deploy.py -nf -dea ~/CONF/virtual/dea.yaml -dha ~/CONF/virtual/dha.yaml -nh -log ~/Deployment-888.log.tar.gz
 
 
 - Install Fuel Master only (and Node VMs when using virtual environment):
 
     => for virtual environment:
-    sudo python deploy.py -iso ~/ISO/opnfv.iso -dea ~/CONF/virtual/dea.yaml -dha ~/CONF/virtual/dha.yaml -s /mnt/images
+    sudo python deploy.py -iso ~/ISO/opnfv.iso -dea ~/CONF/virtual/dea.yaml -dha ~/CONF/virtual/dha.yaml -s /mnt/images -log ~/Deployment-888.log.tar.gz
 
     => for hardware environment:
-    sudo python deploy.py -iso ~/ISO/opnfv.iso -dea ~/CONF/hardware/dea.yaml -dha ~/CONF/hardware/dha.yaml -s /mnt/images -b pxebr
+    sudo python deploy.py -iso ~/ISO/opnfv.iso -dea ~/CONF/hardware/dea.yaml -dha ~/CONF/hardware/dha.yaml -s /mnt/images -b pxebr -log ~/Deployment-888.log.tar.gz
 
 
 - Cleanup a running OPNFV environment:
