Re: Refactored code for Table and its child nodes.

Hi Hackers,

For a couple of days, I was working on the code refactoring of Table and it's child nodes.

Problem:  In pgAdmin4 child nodes of the table can be created/modified from table dialog as well as from individual node. For example: Primary Key constraint can be created/updated from tables as well as from individual primary key node.

After analyzing the code it seems that we have duplicate logic/functions in 'tables/utils.py' and '__init__.py' of the respective node. 

So because of the above-described problem, if there is a bug at one place we need to fix it on both the places.  

Purpose: 

1. Remove duplicate logic.
2. Child node specific logic should be inside the child node and table node gets the required information from the respective child node.

Solution:

1. Create 'utils.py' for each child node.
2. Move the common logic from 'tables/utils.py' and '__init__.py' of the respective node to 'utils.py'.
3. Both table and its respective child access the functions from the respective 'utils.py'.

Note: Refactoring of columns node still remaining I'll start working on it.

Please review/test the patch thoroughly for tables and it's child nodes.
