"type" is a builtin in python; switch some arguments called "type" to be "type_"

[dan98765]

Closes #700

Also:

• Underscore prefix generally is understood to mean 'private' more than just 'not a builtin' so changed type to type to be consistent.
• Add aniso8601 dep to tox.ini to get tests to pass

@jkimbo how do you feel about this branch?

[jkimbo]

I like it. It's technically a breaking change so lets try and get it in 2.2 with the _resolve_type change as well.

@dan98765 needs rebase

[jkimbo]

Since it’s a breaking change it should probably be part of a 3.0 release (instead of 2.2 as I suggested earlier). Do you agree @graphql-python/governors ?

[Cito]

@jkimbo I'm also using type_ instead of type in graphql-core-next, so this would be consistent.

[mvanlonden]

Approving but wait until ready for 3.0 release, should be merged alongside #775
