Update Pylint config file for development

Current Tacker repository contains .pylintrc, which is a configuration
file of Pylint [1].

[1] https://pylint.org/

However, it is not maintained for 8 years ago,
so it contains some out-of-date configurations
for current Pylint version.

This patch removes those out-of-date configurations,
and introduces some useful configurations for IDE integration.

+-------
+
+Tacker project supports the configuration of `Pylint`_, a lint tool for
+Python code.
+
+You can get Pylint CLI tool from PyPI:
+
+.. code-block:: console
+
+    $ pip install pylint
+
+Then you can check your code with Pylint like:
+
+.. code-block:: console
+
+    $ pylint path/to/code
+
+If you want to check the entire Tacker code:
+
+.. code-block:: console
+
+    $ pylint tacker/
+
+``.pylintrc`` in Tacker repository root is a configuration file of Pylint.
+
+If you want to check Pylint messages, detailed CLI configurations
+and configurations in ``.pylintrc``, please refer to
+`Pylint official reference`_.
