Disable coalesce for status updates, and requests
v0.0.1.alpha19

= Bug fixes

- [CRIT] Disable event coalascing for status updates and requests.
  In default `serf event` coalesces events having same name. So same status
  updates from several hosts might be dropped by serf itself.

  Starting from this release, basically coalescing is disabled to fix
  that issue.

= Enhancements

- Log agent's fetch failures on master side.
