Update functions to 3.0 (#4910)

This reverts commit 3ab67a3.
Filters out bin folder when running tests to fix the tests failure issue. It's not clear why only in some runs the bin folder has the test dlls and not the runtimeconfig.json files which is causing the tests run to fail. Other times it was passing because the bin folder didn't contain the test dlls when running on different pipeline agent (but using same dotnet sdk and everything else looked the same)

+# Azure functions module for IoT Edge
+This is a sample on how to use EdgeHub binding for Azure functions in an IoT Edge module. 
+It contains a C# function that gets triggered when a message is received from EdgeHub and also contains docker files needed to build the module image.
+
+Current version is based on Azure functions runtime 3.0 which has a larger docker image size compared to previous version. If image size is a concern older version of EdgeHub binding (<=1.0.7) has to be used which is based on Azure functions 2.0
