### Feature description

Hello team. Please, kindly work on this feature for awslocal CLI:

awslocal es update-elasticsearch-domain-config --domain-name my-domain --region us-east-1 \
      --advanced-security-options '{ "Enabled": true, "InternalUserDatabaseEnabled":true, "MasterUserOptions": {"MasterUserName":"master-username","MasterUserPassword":"master-password"},"AnonymousAuthEnabled": true}'
      
 Right now it returns the following response:
 
An error occurred (InternalFailure) when calling the UpdateElasticsearchDomainConfig operation: API action 'UpdateElasticsearchDomainConfig' for service 'es' not yet implemented
 
 Thank you,
 Victor
