injector's database management endpoints to create and delete Redis databases during E2E testing. + +## Overview + +The fault injector now supports two new endpoints for database management: + +1. **CREATE_DATABASE** - Create a new Redis database with custom configuration +2. **DELETE_DATABASE** - Delete an existing Redis database + +These endpoints are useful for E2E tests that need to dynamically create and destroy databases as part of their test scenarios. + +## Action Types + +### CREATE_DATABASE + +Creates a new Redis database with the specified configuration. + +**Parameters:** +- `cluster_index` (int): The index of the cluster where the database should be created +- `database_config` (object): The database configuration (see structure below) + +**Raises:** +- `CreateDatabaseException`: When database creation fails + +### DELETE_DATABASE + +Deletes an existing Redis database. + +**Parameters:** +- `cluster_index` (int): The index of the cluster containing the database +- `bdb_id` (int): The database ID to delete + +**Raises:** +- `DeleteDatabaseException`: When database deletion fails + +## Database Configuration Structure + +The `database_config` object supports the following fields: + +```go +type DatabaseConfig struct { + Name string `json:"name"` + Port int `json:"port"` + MemorySize int64 `json:"memory_size"` + Replication bool `json:"replication"` + EvictionPolicy string `json:"eviction_policy"` + Sharding bool `json:"sharding"` + AutoUpgrade bool `json:"auto_upgrade"` + ShardsCount int `json:"shards_count"` + ModuleList
