Checkmk Werk 13698: Deprecate configuration variable 'agent_min_version'

ID: 13698 Title: Deprecate configuration variable 'agent_min_version' Component: Checks & agents Level: 1 Class: New feature Version: 2.1.0b2 This Werk only affects users that used a <tt>.mk</tt> file to configure the variable <tt>agent_min_version</tt>. It has never been configurable via <i>WATO</i>. The configuration variable 'agent_min_version' does not have any effect anymore. Setting the variable to an integer other than 0 (the default) lead to a crash, setting it to a string lead to unreliable behaviour. If you want to check the version of the installed agent, please configure a rule in the ruleset <i>"Checkmk Agent"</i>.
