[Refactoring] Make command definition compact

[iboss-ptk]

Currently defining new command or changing old command interface needs to edit entrypoint and ops modules.

The purpose of this refactoring it to

• make command definition compact, one place change
• has clear framwork to deal with recurring job like
  • using value in config as default
  • recurring transformation due to clap only accept string, there are steps for transforming input into non primitive eg. gas
  • using type wrapper with fn for recurring transformation?
  • query / tx, could even create QueryCmd, TransactionCmd kinda type to bundle all this logic together eg. broadcasting, simulation and such and has the basic args for query / tx in the struct so they can parse the cmd input.
  • reusable simulation logic, so that all the tx type command are simulate-able from the get go.

Benefits

• code organization and faster iteration
• testing will be easier to organize, which means it helps for better code cov and confidence in not breaking stuffs without test locking you from easy changes.

#[derive(Subcommand,Hook)]

  /// Name of the contract to instantiate
  contract_name: String,
  /// Label for the instantiated contract for later reference

  label: String,

  /// Raw json string to use as instantiate msg
  #[clap(short, long)]
  raw: Option<String>,

  /// Specifying admin required for contract migration.
  /// Use "signer" for setting tx signer as admin.
  /// Use bech32 address (eg. "osmo1cyyzpxplxdzkeea7kwsydadg87357qnahakaks") for custom admin.
  #[clap(long)]
  admin: Option<String>,

  /// Funds to send to instantiated contract
  #[clap(short, long)]
  funds: Option<String>,

  #[clap(flatten)]
  tx_cmd: TransactionCmd, // this comes with simulation hook, needs to `impl Hookable for TransactionCmd`
}
