Closes-Bug: #1545618 : Upgrade of contrail from R2.23 to mainline fixed

Changes:
I. Cassandra upgrade thru intermediate 2.0 version
Cassandra configured using file_line (not templates)
Cassandra templates removed

II. Python-kafka-python package replaced by python-kafka package

III. Contrail-config package brings new configs, causes dependency issues - fixed

IV. Removed secret key from nova api (metadata services bug)

Closes-Bug: #1543333

Patch 2:
Closes-Bug: #1550650 - Error in Cassandra Seeds
Closed-Bug: #1550665 - Error in wget of upgrade_cassandra script

Patch 4:
Changes to config_cassandra (to remove extra cofigs which cause error in multinode)
Changes to database/install.pp (use contrail::params::contrail_repo_name - smlite CI failure)

Closes-Bug: #1550650 - Previous Upgrade cassandra script has bugs

1. The previous shell script did not loop properly to check for connect status
It was succeeding in cases where cassandra comes up within five seconds only

2. Config cassandra had bug in one particular file_line

3. Added dependency for upgrade such that contrail-database package gets upgraded only if cassandra upgrade succeeds

Note:
upgrade_cassandra.sh can be run independently to upgrade cassandra before provision
Usage is:
./upgrade_cassandra.sh <host_ip> <cassandra_home_dir> <image_id of added 3.0 image>
