Support for automatic retry

[hexoul]

Motivation

• Apply retryer to BaseClient
• #46

Modifications

• Use third-party library, tenacity, to retry at client. It helps to reduce boiler plate and feature implementations such as exponential backoff.
  • Add related tests, test_get_with_retry_by_response, test_get_with_retry_by_client at "test_base_client.py".
• Bump version to 0.4.0
  • @ikhoon After this PR, I would like to publish 0.4.0. If you have different opinion, please tell me about the idea.
• misc.
  • Refactor not to write repetitive hard coded.
  • Apply retries option for integration test client for flaky tests. #42

Result

• Close #46

if main branch testing fixed. I think it's good to deploy

@darjeeling I hope so. It may help tests to be more robust. Still tests for watch seems flaky though.
