KeyError: 'node_config_details'

Looking the source code I see there is no initialization of node_config_details (missing: kwargs['node_config_details'] = {} ):

The workaround is to set the size parameter: --size
, because this parameter initializes the node_config_details array, however, this has an impact by changing the size (although it can be the same, but adds unnecessary overhead).

Start in services/container_engine/src/oci_cli_container_engine/containerengine_cli_extended.py at update_node_pool, where node_config_details is accessed while handling node_defined_tags. Reproduce the reported node-pool update without --size and verify that defined tags can be updated without a KeyError or unnecessary size change.
