Highlight packages

[clemgbld]

The latest version of the NodeSecure scanner can highlight a given list of packages (see the highlight.packages option in the cwd / from commands and highlighted.packages in the result payload).

However, this feature is not yet exposed in the CLI or the UI.

I see several possible improvements:

• Add a new CLI argument to provide packages to the auto and cwd commands.
  These commands expect a record, so we need to define a convenient CLI format (for example: key value key value key value). We would also need to validate the semver values provided as input.
  In the future, we could allow passing a path to a CSV or JSON file, which would be more convenient for long lists of packages.

• add an option in the search to retrieve the highlighted packages.

By validating semver, do you mean an official semver format validator ? maybe something already exists.

As a cli argument, i think we should let user enter a classic package like express@1.5.7 instead of enforcing a "technical" data structure. then the validator could return a record as needed. an evolution of mama specParsing function for example.

what do you think ?

@ErwanRaulo since this dev NodeSecure/scanner#587 the scanner can now accept an array of specs as input for the packages to highlight, i think this is the easiest format to support atm for the cli.
maybe be just validate that the specs are valid.
