Gather and expose errors

[mamo3gr]

Motivation

Gokart users catch some errors to deal with them according to the errors' details in their applications. But exceptions of this library exist (and will be created in the future) in each sub-module. Users would need to locate their desired exception and keep it in mind.

Proposal

Errors should be gathered and exposed in gokart.errors module.
Descriptions would be helpful for the users.

Discussion

Moving actual implementations or aliasing

By now, I think it is sufficient to just alias the exceptions (import them from gokart.errors module) because existing exceptions are raised from a single source in many cases, and they are located near the source (raiser).

Location to gather

As an alternative way, exceptions can be located under gokart module. In that case gokart.__init__.py would be a little messy.

• Adding descriptive docstrings to existing exceptions in gokart/pandas_type_config.py, gokart/build.py, and gokart/task.py.
• Updating gokart/slack/init.py to include new error types along with existing components.
