Review request for Ambari, Alejandro Fernandez and Nate Cole.


Bugs: AMBARI-12228
    https://issues.apache.org/jira/browse/AMBARI-12228


Repository: ambari


Description
-------

Here is an example of the new orchestration for an upgrade from 2.2 to 2.3

- Before Upgrade Begins
-# Execute a custom script to stop all oozie servers, one at a time
-# Execute the database upgrade using the 2.3 bits
-# Execute the sharelib creation and upload using the 2.3 bits

- For each Oozie server, which is currently down
-# backup the oozie configurations
-# conf-select and hdp-select
-# restore configurations
-# Prepare /usr/hdp/current/oozie/libext-customer and gets ready to upgrade the WAR
-# {oozie_setup_sh} prepare-war {oozie_secure} -d {oozie_libext_customer_dir}
-# Start the Oozie server

On a downgrade, we will perform a similar series of steps, except a few differences:
- No database upgrade will be performed
- The bits used to generate the sharelib are going to be the downgrade stacks, ie 2.2
