[refactor]: Change code organization in `iroha_client_cli`

[Erigara]

Btw, it seems that context is used only within submit and listen functions. So, maybe you can define a "miniclient" struct that has submit and listen functions, and does the printing internally?

trait MiniClient {
  fn listen(&mut self, height: NonZeroU64) -> Result<()>;

  fn submit(&mut self, isi: impl Into<Executable>, metadata: UnlimitedMetadata) -> Result<()>;
}

RunArgs might work with MiniClient trait. The struct that implements MiniClient might contain both configuration and debugging logic, which RunArgs does not care about.

@0x009922 is this still relevant?
