cluster: major upgrade procedure (#51)
Current patch version upgrade procedure is ran when cluster is being upgraded to next patch version. New major upgrade procedure handles all others upgrades. Procedure: * Check if the cluster has schema agreement (using API call) * Take `system` and `system_schema` tables snapshot on all nodes in parallel. For each node: * Drain node * Backup the data - snapshot of all data keyspaces * Update Scylla image by restarting Pod * Validate if node is up and version is updated via API call * Clear data snapshot After last node: * Delete `system` and `system_schema` table snapshots on all nodes in parallel Fixes #51
