[ClusterLabs] Coming in 1.1.15: recurring stop operations

[Ken Gaillot]

In current versions of Pacemaker, trying to configure a stop operation
with a time interval results in a warning about an "invalid configuration."

A popular request from the community has been to enable this feature,
and I am proud to announce recurring stop operations will be part of the
future 1.1.15 release.

A common situation where a recurring stop operation is required is when
a particular provided service is funded in the budget for only part of
the time. Now, configuring a stop operation with interval=36h allows you
to stop providing the service every day and a half.

Another common use case requested by users is to more evenly distribute
the staff utilization at 24-hour NOC facilities. With a interval=8h stop
operation, you can be sure that you will get your salaries' worth from
every NOC shift.

Lastly, some users have requested sysadmin training exercises. With this
new feature, it is possible to use rules to apply the interval only
during conditions of your choosing. For example, you can set a 2-hour
stop interval to apply only during full moons that occur on a Friday.
That will give a thorough disaster training workout to your new sysadmins.
