Init Cassandra Keyspace and Tables

[alexanderkiel]

We should init the Cassandra key space and tables from within Blaze instead of using an init container. The init Script looks like this:

CREATE KEYSPACE blaze WITH REPLICATION = {'class': 'SimpleStrategy', 'replication_factor' : 2};
CREATE TABLE blaze.resources (hash text PRIMARY KEY, content blob);
CREATE TABLE blaze.clauses ("token" text PRIMARY KEY, content blob);

The init container:

 cassandra-init-data:
   image: "cassandra:5.0.6@sha256:5e2c85d2d5db759c28c3efb50905f8d237f958321d6dfd8c176cb148700d9ade"
   command: "cqlsh -f /scripts/cassandra-init.cql"
   environment:
     CQLSH_HOST: "cassandra-1"
   volumes:
   - "./cassandra-init.cql:/scripts/cassandra-init.cql:ro"
