Review request for Ambari, Alejandro Fernandez and Jayush Luniya.


Bugs: AMBARI-14435
    https://issues.apache.org/jira/browse/AMBARI-14435


Repository: ambari


Description
-------

Apply the  stack featurization prototype  detailed on AMBARI-13364 to ZOOKEEPER 
service.
This patch removes the hardcoded stack versions in ZK common-services code 
(centralized version and parameterized stack configurations will be faced in 
other JIRAS)
stack_features is now a property in .json format in 
configuration/cluster-env.xml for each stack version.
With the structure:
{
"stack_features": [
{ "name": "feature1", "description" : "Feature1 support", "min_version" : 
"Y.Y.Y.Y" , "max_version" : "X.X.X.X"}
, 
...
]
}
where min_version/max_version are optional constraints.
New resource_management/libraries/functions/stack_fetaures.py has been 
introduced to parse the json file and called from service code to check if the 
stack supports the required feature.
