HTMLParser + Slack API + MySQL in python

First, create a database with a table named "notices".

CREATE TABLE notices (
  id INT,
  title VARCHAR(100),
  date VARCHAR(30),
  link VARCHAR(101),
  writer VARCHAR(25)
)

Added a test which contains filtering function (it'll filter notices within the array of strings)

Made producer more safe and highthroughput.

Added old notices remover in producer.

Added a little bit of resting time between consuer polling.

Before: some notices have their name in notices

[writer]: [writer] title

After: remove writer in titles

[writer]: title
