Some API calls just sent but the results were uncertain, Horizon should notify the user that your request is just accepted, not successfully. So this patch change some form message level to INFO, and some message expression. Change-Id: I241cd9cf3ad6b2bd747e3ea1c6040a140ba77b56 Closes-Bug: #1326301 Closes-Bug: #1286418
