Gregory Thiemonge 0a9f587015 Fixed down server issue after reloading keepalived
When removing a UDP health monitor, keepalived is reloaded with a
configuration without any checkers.
But if keepalived has previously detected a down server, the state of
the server is unchanged and it will never be added to the list of IPVS
servers.

Restarting keepalived on configuration change works around this issue.

This issue is fixed in keepalived (>=2.0.14):

When a load balancer with a UDP listener is updated, the listener service
is restarted, which causes an interruption of the flow of traffic during a
short period of time. This issue is caused by a keepalived bug
(https://github.com/acassen/keepalived/issues/1163) that was fixed in
keepalived 2.0.14, but this package is not yet provided by distributions.
fixes:
- |
Fix a bug that prevented UDP servers to be restored as members of a pool
after removing a health monitor resource.
