* feat(namespaces): Initial support for multi-tenant #3050 This PR introduces a way to create multiple, separate and isolated namespaces in Dragonfly. Each user can be associated with a single namespace, and will not be able to interact with other namespaces. This is still experimental, and lacks some important features, such as: * Replication and RDB saving completely ignores non-default namespaces * Defrag and statistics either use the default namespace or all namespaces without separation To associate a user with a namespace, use the `ACL` command with the `TENANT:<namespace>` flag: ``` ACL SETUSER user TENANT:namespace1 ON >user_pass +@all ~* ``` For more examples and up to date info check `tests/dragonfly/acl_family_test.py` - specifically the `test_namespaces` function.
