Diff updated according to comments. Falcon-related code was moved to configure() method of
oozie. Also, patch was tested on multinode cluster.


Bugs: AMBARI-4263
    https://issues.apache.org/jira/browse/AMBARI-4263


Repository: ambari


Description
-------

Added new service(FALCON). It was split it into 3 components: Falcon Service, Falcon Client,
Falcon Oozie EL. Falcon Oozie EL must be installed on host with Oozie Server(Oozie Server
must be stopped before install). Currently only main parameters(see global.xml) are configurable(to
prevent changing important properties like implementation classes).
