oc4.0: fix cassandra.backup
As the yaml parsing python script never got into the
container in several cases cassandra ip was not properly
retrieved making it impossible to create a backup.
Another issue with wrong port used for OC4.0 was fixed
by taking the correct one from cassandra config.
This patch introduced some refactoring substituting the
not-so-meaningful script for an inline call to python
yaml parser to fetch params from cassandra config and
using env vars in runner script instead of duplicating
code.
