Обсуждение: #2483 - Add pgAdmin users via a CLI or script call

Hello hackers,

I am working on #2483 - Add pgAdmin users via a CLI or script call.

As we want a consistent and centralised CLI, I suggest replacing Argparse with the Typer package.

The main advantage of the Typer is that it decreases the complexity and is built upon CLICK, the most used library for Python CLI.

We will use the setup.py file for all the CLI modules; we can introduce one function per CLI feature (per command) as described below.

So, the below line will cover all the combinations of Load server functionality.

@app.command()
def load_servers(loadservers: str, user: Optional[str] = None, sqlite_path: Optional[str] = None, replace: Optional[bool] = False):

The command will be like this:

python setup.py load-servers test.json

python setup.py load-servers test.json --replace      

python setup.py load-servers a.json --user 'test@gmail.com' --replace      

======================================================================

An example of reducing complexity:

ArgParse code:

if __name__ == '__main__':
    # Configuration settings
    parser = argparse.ArgumentParser(description='Setup the pgAdmin config DB')

    imp_group = parser.add_argument_group('Load server config')
    imp_group.add_argument('--load-servers', metavar="INPUT_FILE",
                           help='Load servers into the DB', required=False)
    imp_group.add_argument('--replace', dest='replace', action='store_true',
                           help='replace server configurations',
                           required=False)

    imp_group.set_defaults(replace=False)

    args, extra = parser.parse_known_args()

    # What to do?
    if args.dump_servers is not None:
        try:
            dump_servers(args)
        except Exception as e:
            print(str(e))
======================================================================

Equivalent Typer code:

@app.command()
def load_servers(loadservers: str, user: Optional[str] = None, sqlite_path: Optional[str] = None, replace: Optional[bool] = False):
    .......
app = typer.Typer()
if __name__ == "__main__":
    app()


If anyone has any suggestions/questions, do let me know.
