[PR] : psycopg2 to asyncpg

[code-chaser]

Changes:

• Fixes [BUG] : psycopg2 is not async #23
• Created a dict to store the data from the online database so as to avoid querying the database for every single query;
  • Format of the dict:

    {
        'guilds': {
            '<guild1_id>': {'prefix': '<coressponding_value>', 'tag_messages': '<coressponding_value>'},
            # for each record in the table
        },
        # for each table in database
    }

  • Implementation:

  self.DATABASE['guilds'] = {result['guild_id']: {k: v for k, v in result.items() if k != 'guild_id'} for result in await self.DB_CONNECTION.fetch("SELECT * FROM guilds")}

• Added a new bot command:
  • prefspace: toggles the trailing space in the bot prefix;

Closing Pull Request

Reason for closing:

• This branch had an error being deployed;
• Build Log / Error:

       The conflict is caused by:
           - The user requested aiohttp==3.8.1
           - discord-py 1.7.3 depends on aiohttp<3.8.0 and >=3.6.0
  

Solution:

• change version of aiohttp from 3.8.1 to 3.7.4;
