[feature] Validate INPUT.json against INPUT_SCHEMA.json when testing locally

[remyoucef]

It would be super helpful to add a command to validate the INPUT.json file against the INPUT_SCHEMA.json file.

This will help us avoid doing input validation via code when testing the actor locally.

Also, It allows validating the input before calling the actor on the platform (apify call).

Closing in favor of #66 and we have command apify vis to validate input
