Hello,

In mongoengine the name 'meta' is used to attach metadata to the Document.
I have a problem with this name as all of my documents in MongoDB have this field and I cannot use mongoengine for this reason.

Is there a workaround for this?

Would you accept a breaking change where the meta field is renamed?
class MyDoc(Document): metadata = { "max_documents": 100 }

Now of course renaming the meta name to something else might break it for others.
Would you accept a breaking change where the meta field is replaced with a "Meta" class
class MyDoc(Document): meta = StringField() class Meta: max_documents = 100

While not trivial, the actual change would probably not be that bad to make. I have a test where I could initialize MyDoc with the 'class Meta' style.
If there is support for such a change, I would be happy to make it.
