Closes-Bug: #1550650 - Re-entrant Upgrade cassandra script and upgrade fixes

Closes-Bug: #1545618 - Duplicate upgrade bug
This change:
1. Fixes upgrade_cassandra.sh to be re-entrant
2. Changes one augeas_conf_set to file line (needed as value itself has quotes)
3. Delete of additional package: contrail-openstack-analytics needed for old python-kafka upgrade issue
4. appended File_line[‘’] to subscribe in upgrade_kernel.pp because some scripts ran before upgrade in Shashi setup
5. Changed one file_line to exec in config_cassandra (already merged in mainline)
