feature: Support meltano test for taps

[edgarrmondragon]

Feature scope

CLI (options, error messages, logging, etc.)

Description

Problem

The meltano test CLI uses plugin commands to run tests for one or more plugins. However It's not working great at the moment for taps because Meltano doesn't know that it also needs to pass other options, like --config, so it fails if config is required.

Proposal

• Add a new boolean pass_plugin_args field to the Command object.
• Update PluginInvoker.exec_args to call self.plugin.exec_args, if command_config.pass_plugin_args is true.

meltano/src/meltano/core/plugin_invoker.py

Lines 292 to 298 in d59a7c9

	if command:
	command_config = self.find_command(command)
	plugin_args = command_config.expanded_args(command, env)
	if command_config.executable:
	executable = self.exec_path(command_config.executable)
	else:
	plugin_args = self.plugin.exec_args(self)

This will allow Meltano to call tap-example --config ... --test under the hood.

With that, the following config

plugins:
  extractors:
  - name: tap-stackexchange
    variant: meltanolabs
    pip_url: git+https://github.com/MeltanoLabs/tap-stackexchange.git
    commands:
      test:
        pass_plugin_args: true
        args: --test

should allow meltano test tap-stackexchange to work as expected.
