Download configured package manager and run it

[timotheeguerin]

fix #5687

Features

• respect the packageManager(Format <packageManager>@<version> or <packageManager>@<version>+<algo>.<hash>) and devEngines.packageManager field
• packages are be downloaded from the public npm registry
  -no support yet for proxy, private registries, using the node route is always available for those cases
• ability to save a hash of the packagemanager in the field which is used to validate the .tgz file match.
• new flag --save-package-manager which populate the packageManager field with the resolved version and the hash.

Only support npm for now. Adding support for yarn and pnpm should be quite simple.
