Allow plugins to override built in commands

[tom-sherman]

Describe the Feature

Commands and healthchecks defined in the config should override built-in commands so that I can, for example, provide my own react-native start command implementations.

This would allow repack to override the start command instead of requiring an alternative webpack-start cmd.

Possible Implementations

I believe it requires flipping the order here:

cli/packages/cli-config/src/loadConfig.ts

Line 146 in ae056a1

commands: [...acc.commands, ...config.commands],

However I tried this and it didn't allow me to override start.

Related Issues

This would offer a first party solution to nrwl/nx#20847

Hey @tom-sherman, I think we can add support for this! Also for Re.Pack it will solve one other problem - when we're running run-ios we're also starting new window where we run start command, and in most cases it opens Metro instance which can be confusing for non-advanced users 😅 cc @jbroma
