Bug Fixes for NetEye 4.22

We fixed a bug which could cause Icinga 2 to not behave correctly when the Smart Director was enabled. This bug was occurring when Icinga 2 started before the DRBD of Icinga Web 2 was started. For NetEye 4.22 we updated the following packages: icinga2, icinga2-autosetup, icinga2-bin, icinga2-ido-mysql, icinga2-neteye-config, icinga2-resources, icinga2-common, icinga2-selinux to version 2.11.9_neteye1.48.3-1
