[Feature Request] Global dependency

[paulo-raca]

Hello, and thanks for this great project.

My current project has a lot of different tasks, and all of them depend on some common setup action/checks, like "checking that required tools are installed", etc. E.g.,

tasks:
  verify_tools:
    preconditions:
      - sh: "command -v docker"
        msg: |
          You don't have docker installed.
          Please check https://docs.docker.com/engine/install/

Instead of adding this as a dependency everywhere (easy to forget), It would be nice if we could mark it as global dependency, either using a special task name or a flag.

setup_task: verify_tools```

tasks:
setup: # Special task name
deps: [verify_tools]

Feel free to open an issue to track this. You're basically asking for #294, but via a global dep rather than a having a direct global precondition. I think this is actually more flexible/powerful than #294 is.

Also related:

• Add task hooks #667 - Hooks
• Add a "setup:" setting to allow running setup scripts before any command? #204 - A set of setup/cleanup commands

I think this is different to either of those though since you're talking about a task that does some external setup rather than one that runs as a hook before each command (i.e. to configure some shell env etc)
