Check_MK Werk 7155: Ended Support for SLES 11 in version 1.6

ID: 7155 Title: Ended Support for SLES 11 in version 1.6 Component: Linux Distributions Level: 1 Class: New feature Version: 1.6.0i1 Since SLES 11 are using a OpenSSL version before 1.0.0 we decided to end the support for SLES 11 for our next release. Many Python packages, that are used in Check_MK are dependent on newer OpenSSL versions. An old OpenSSL version is not only a security risk but also a threat for compatibility and stability.
