`ConfigType::GetObjectsByType<Downtime>()` already returns a
`std::vector<Downtime::Ptr>` so there is no point in copying it into another
vector of the same type just to then iterate the copied vector instead of the
original one.
This commit fixes the following build error:
[ 55%] Building CXX object lib/icinga/CMakeFiles/icinga.dir/usergroup.cpp.o

Many functions of LegacyTimePeriod take a tm pointer as an input parameter and
then pass it to mktime() which actually modifies it. This causes problems if
tm_isdst was intentionally set to -1 (to automatically detect whether DST is
active at some time) and then a function is called that implicitly sets
tm_isdst and then the values of tm are modified in a way that crosses a DST
change. This resulted in 1 hour offsets with ScheduledDowntimes on days with
DST changes.
* Implement scheduling_source attribute
This implements the attribute `scheduling_source` for hosts and services to show which endpoint is running the scheduler for the check.

Only handle messages with a trusted origin in
ClusterEvents::ExecuteCommandAPIHandler. Previously, it would not locally
execute any command but forward them to other nodes where they would then have
a trusted origin and be executed.
Note that even when passing `nullptr` as target zone to `RelayMessage()`, the
cluster message will still be sent to the parent zone. These incoming messages
will now be rejected by the parent nodes. At the moment, there's no way to only
send within the local zone.
Disregard passive check results while no active checks are being scheduled due to violated dependencies.
This copes with the fact that programs feeding passive check results into Icinga may have no notion of reachability and so drive a checkable into HARD state although dependencies have caused active check scheduling being suspended. This may prevent superflous problem notifications being emitted during recovery.
As disable_checks defaults to false, it was regarded OK (by @Al2Klimov) to make this behaviour (which resembles the active check case) unconditional and not conditionalize it on an additional attribute.
In the description of disable_checks, note that a value of true both disables scheduling of active checks and drops passive check results.
At numerous places in the code, something like this is performed:
String name = Downtime::AddDowntime(...);
Downtime::Ptr downtime = Downtime::GetByName(name);
However, `downtime` can be a `nullptr` after this as it is possible that
the downtime is deleted in between.
This commit changes the return type of `Downtime::AddDowntime` to return
a Downtime::Ptr instead of the full name of the downtime. `AddDowntime`
performs the very same `GetByName()` operation internally, but handles
the `nullptr` case correctly and throws an exception.
`this` could be deleted after `Notification::BeginExecuteNotification`
exited and before `Notification::ExecuteNotificationHelper` finished.
This is fixed by constructing a `Notification::Ptr` and operate on that
one as it is properly reference-counted.
Only two out of three cases were handled properly by the code: host
downtimes referencing a deleted host and service downtimes referencing a
deleted service worked fine. However, if a service downtime references a
deleted host, `Host::GetByName()` returns `nullptr` which isn't
accounted for. Use `Service::GetByNamePair()` instead as this performs a
check for the host being null internally.
