[v9_16] Disable PyLint warning C0209
PyLint 2.11 reports a new warning, C0209 (consider-using-f-string). Since f-strings are only available in Python 3.6+, existing scripts cannot be updated to use this feature just yet because they would stop working with older Python versions. Instead, disable PyLint warning C0209 for the time being. Sort all disabled warnings in .pylintrc.
