pgAdmin 4 commit: Adding the Database node.

Adding the Database node.

We know that current implemenation have some limitations:
i.e.
* We should not show the template0 in the browser tree.
* Should not connect to the database which does not have permission to connect the server by the current user.
* Show default previlige for PUBLIC in creation mode.
* Allow to create/database database only if current user have sufficient permission.
* Do not show reversed engineered SQL in all supported version.
* Do not showing system database or not.
