Allow modifying the actor root path

[jeanbmar]

Hey there,

I use a monorepo with NPM workspaces:

project
+-- node_modules
+-- packages
    +-- shared-lib
    +-- actor
        +-- apify.json

The apify push command is run from the actor directory.
Apify client uses the actor folder as root path as seen here:

apify-cli/src/commands/push.js

Line 67 in 6222bd0

const filePathsToPush = await getActorLocalFilePaths();

This is preventing a proper installation of the shared-lib when container runs npm install because the lib is not bundled.

Could we have a new option in apify.json to allow a custom root path?
