Something is definitely going wrong if a client tries to reconnect to
this endpoint while it still has an active connection to that client. So
we shouldn't hide this, but at least log it at info level. Apart from
that, I've added some additional information about the currently active
client, such as when the last message was sent and received.
This is a good alternative to `icinga2 feature enable debuglog`:
* Object creation/deletion via API happens immediately and requires no restart
* Hence, the debug log is enabled exactly as long as desired

The Redis ACL system was introduced with Redis 6.0. It introduced users
with precisely granular permissions. This change allows Icinga 2 to use
the Icinga DB feature against a Redis with an ACL user.
This was reflected in the documentation, next to the already
implemented, but undocumented Redis database.
Closes#9536.
Each configuration field of an IcingaDB Object was marked with
no_user_modify as modifications via the API would not result in an
actual change. While the Object would be updated, the internal Redis
connection would not be restarted, resulting in an unexpected behavior.
The missing db_index was added to the documentation.
The previous validation in set_verify_callback() could be bypassed, tricking
Icinga 2 into treating invalid certificates as valid. To fix this, the
validation checks were moved into the IsVerifyOK() function.
This is tracked as CVE-2024-49369, more details will be published at a later time.
This fixes an issue where recovery notifications get lost if they happen
outside of a notification time period.
Not all calls to `Checkable::NotificationReasonApplies()` need
`GetStateBeforeSuppression()` to be checked. In fact, for one caller,
`FireSuppressedNotifications()` in
`lib/notification/notificationcomponent.cpp`, the state before suppression may
not even be initialized properly, so that the default value of OK is used which
can lead to incorrect return values. Note the difference between suppressions
happening on the level of the `Checkable` object level and the `Notification`
object level. Only the first sets the state before suppression in the
`Checkable` object, but so far, also the latter used that value incorrectly.
This commit moves the check of `GetStateBeforeSuppression()` from
`Checkable::NotificationReasonApplies()` to the one place where it's actually
relevant: `Checkable::FireSuppressedNotifications()`. This made the existing
call to `NotificationReasonApplies()` unneccessary as it would always return
true: the `type` argument is computed based on the current check result, so
there's no need to check it against the current check result.
`m_IsNoOp` was introduced to avoid building up log messages that will later be
discarded, like debug messages if no debug logging is configured. However, it
looks like the template operator<< implemented in the header file was forgotten
when adding this feature, all other places writing into `m_Buffer` already have
an if guard like added by this commit.

We instruct the users to build as root and chown just /usr/local/icinga2/var, but at least `icinga2 api setup` also needs to modify /usr/local/icinga2/etc.
