2.11 rc1: built-in check command "icinga" doesn't work with version compare

[stevie-sy]

Describe the bug

At our test Cluster (2 master, 4 satellite in 2 zones) the built-in check command "icinga" with the performance-data doen't work like before:

this error we got on every node.

To Reproduce

define the build in check-command "icinga" on the icinga Server and after a check you get this message.

Expected behavior

The check should work like before. e.g. 2.10.5

BTW: Other built-in check commands like "ido", "cluster" work like before.

Your Environment

• Operating System and version: CentOS 7.6.1810

Try removing icinga_min_version while testing the RC with a different version format. Seems the version detector needs a fix in there for "abnormal" versions.

[stevie-sy]

perfect, that's it . Whithout the variable "icinga_min_version" it works like before.

[dnsmichi]

Only happens with the RC packages, with a specific version.

[root@icinga2 demo]# icinga2 console --connect 'https://root:icinga@localhost:5665/'
Icinga 2 (version: 2.11.0-0.rc1.1)

<7> => System.ApplicationVersion

Fixed this in the proper way with using regex and adding unit tests for all functions involved.
