Config file of `sea-orm-cli generate entity` command

Motivation

The options and flags for sea-orm-cli generate entity command is getting more and more. It's time to consider a scalable plan: loading the options from a config file.

Proposed Solutions

Load all options by providing the path to the config file: sea-orm-cli generate entity --config generate-entity.config.json. The config file must be a JSON value.

{
    "compact_format": true,
    "expanded_format": true,
    "include_hidden_tables": true,
    "tables": "my_table",
    "ignore_tables": ["seaql_migrations"],
    "max_connections": 1,
    "output_dir": "out",
    "database_schema": "public",
    "database_url": "postgres://root:root@localhost/database",
    "with_serde": "none",
    "with_copy_enums": true,
    "date_time_crate": "chrono",

}

Start at the sea-orm-cli generate entity command entry point and review how its current options are defined and loaded. Use the proposed JSON keys and --config path as the acceptance checklist; done means the config file supplies the listed options for entity generation.
