Support a property to disable extending targetDefault when configuring Nx targets

[MJez29]

Motivation

I recently merged a standalone repo into a monorepo. In the monorepo there is a number of standardized targets (ex. lint) which are defined in nx.json with standardized inputs, outputs and caching. Prior to moving the standalone repo into the monorepo I migrated it onto Nx and created targets that used nx:run-commands and copied the commands from the scripts in the package.json.

When I merged the standalone repo into the monorepo I began experiencing caching issues because the inputs and outputs of the lint targetDefault were unintentionally applying to the standalone repo's lint target. This was undesired behaviour because that specific target was not compatible with the defaults and there is no easy way to opt out

Suggestion

I am suggesting a noTargetDefaults property configurable on a target to disable inheriting target defaults on the target

// nx.json
"targetDefaults": {
  "lint": {
    "inputs": ["foo.ts"],
    "executor": "@nx/eslint:eslint"
  }
}

// project.json
"target": {
  "lint": {
    "noTargetDefaults": true, // `inputs` resolve to the default behaviour: [default, ^default, sharedGlobals]
    "executor": "nx:run-commands"
  }
}
