Querying aliases feature

[rkt2spc]

Following #5184, I now want to implement the ability to query (and update) based on aliased fields. I've been looking at the code for a while. At first, I was looking for ways to apply an option for aliasing on each and every model query. But then, I came up with another solution, which looks something like:

var Foo = mongoose.Model('Foo', FooSchema);

Foo.findOneAndUpdate(
    Foo.translateAliases({aliasedField: ...}),
    Foo.translateAliases({aliasedField: ...})
)

Which I think is neater, clearer, and obviously optional. Plus, this won't change our codebase too much, avoiding cases when we forgot to do conditions aliasing in some queries.

I want to know if you feel okay going down this approach, so I put it here for feedback

translateAliases() would definitely be a great step towards making aliases work seamlessly. If that function works, we can easily add it as a hook and then have it work transparently. Good idea 👍

@rafaelcorreiapoli no, not yet. Will bump this up for the next minor version.

I didn't quite read this thread carefully, it looks like this was fixed by #5338. Here's the docs for Model.translateAlias() @rafaelcorreiapoli
