Deploy all actions within a package

**Is your feature request related to a problem? Please describe.**

I would like to deploy all actions in a specific package, e.g. `aio app deploy -a myPackage/*`

Use-case Example: I may have multiple packages with a total of say 20 actions, but I just want to deploy one package with its 5 actions.

**Describe the solution you'd like**

Options:

- `aio app deploy -a myPackage/*`
- `aio app deploy -a myPackage`

**Describe alternatives you've considered**

We currently can:

1. deploy everything
2. deploy multiple individual actions using multiple `-a`.

**Additional context**

Is there a case when an action is not of the form "${package}/${action}"?

Perhaps `myPackage/*` can be useful in other contexts.
