In origin, get_all_endpoint_states perform all the information formatting and returns a string. This is not a good API approach, this patch replaces the implementation so the API will return an array of values and the JMX will do the formatting. This is a better API and would make it simpler in the future to stay in sync with origin output. This patch is part of #508 Signed-off-by: Amnon Heiman <amnon@scylladb.com>
