This fixes some unusable services of the "HPE Proliant Servers: Raid Status"
plugin.
This werk only affects you if you observe unknown "Logical device
<ITEM>" services after the upgrade.
In case you are affected please run a discovery on the affected hosts and fix the
monitoring history as described below.
We observed some devices to send `""` (the null-byte) as their name (`OID
.1.3.6.1.4.1.232.3.2.3.1.1.14`).
Not all components delt well with it, leading to unacknowlegable downtimes, non matching
rules and the like.
We now replace all null-bytes with `"\x00"` (the literal containing the four
characters backslash, 'x', 'zero', 'zero').
As of Checkmk 2.3, this should in fact no longer be necessary, but as we need a
backportable solution, we change the item consistently in all versions.
If this affects you, you might also want to fix the services in the monitoring history by
running
```
sed -i 's||\x00|' var/check_mk/core/history var/check_mk/core/archive/*
```
