rabbah opened a new issue #407: Add a raw output option to a property queried with "wsk property get"

   When called with no arguments, `wsk property get` shows a table like output:
   
   ```
   whisk auth		BLAH
   whisk API host		openwhisk.ng.bluemix.net
   whisk API version	v1
   whisk namespace		frederic.lavigne@fr.ibm.com_openwhisk-vision
   whisk CLI version	2016-10-24T11:55:02+00:00
   whisk API build		2016-11-08T13:28:31Z
   whisk API build number	whisk-build-1683
   ```
   
   Let's say I want to retrieve the namespace, I can use `wsk property get --namespace`. This output:
   
   ```
   whisk namespace		frederic.lavigne@fr.ibm.com_openwhisk-vision
   ```
   
   Now I have to parse this output to isolate the namespace. This leads to extra `awk` calls like we can see in several advanced OpenWhisk tutorials https://github.com/IBM-Bluemix/openwhisk-darkvisionapp/blob/master/processing/deploy-darkvision.sh, https://github.com/skaegi/openwhisk-package-pipeline/blob/master/deploy.sh
   
   This would go away if the output of the get command was exactly the value of the property with no extra formatting sugar. So instead of 
   ```
   CURRENT_NAMESPACE=`wsk property get --namespace | awk '{print $3}'`
   ```
   I would just do
   ```
   CURRENT_NAMESPACE=`wsk property get --namespace`
   ```
   More readable and less error prone - what if OpenWhisk decides to change the formatting of the output adding more words or spaces, my $3 would no longer match the namespace.
