Check_MK Werk 1158: Moved filter logic to visuals module

ID: 1158 Title: Moved filter logic to visuals module Component: Multisite Level: 1 Class: Bug Fix Version: 1.2.5i6 This change is kind of an internal code restucturing. So if you do not understand this, you mostly do not need to care about it. The filter logic, which was former part of the views, has been moved to the visuals module to be available to all visuals types like dashboards in the future. If you have defined custom filter plugins for your views, which are normally located below share/check_mk/web/plugins/views/*.py, you need to move the filter definitions to share/check_mk/web/plugins/visuals/*.py.
