Feature Request. Validate multiple container types all at once

[windward-hive]

It would be nice to have something like validator.multiple to validate multiple container types all at once rather than having to create a new middleware for each container type.

validator.multiple({
	body: validator.body(),
	params: validator.params(),
	query: validator.params
});

@maybesmurf this could be supported, but the reason I didn't do so is because I wanted to allow a developer to choose the validation order.

Supporting a validator.multiple() is possible, but it would need to use a predefined validation order, e.g headers => query => body, or similar.

I'm not sure what benefit it will provide. WDYT?

I was interested in the same functionality and ended up writing a new package. For anyone interested: https://github.com/mattiamalonni/express-joi-validations

@mattiamalonni I asked in another PR/Issue on this repository if anyone wants to take over as maintainer. If you want, I can add you, and you can implement these changes here. Up to you.
