Propsal: assert_field

[bcardarella]

Currently we have both assert_valid_field and assert_invalid_field

with_changeset(%User{})
|> assert_valid_field(:email, ["test@example.com"])
|> assert_invalid_field(:email, [nil, ""])

it would be nice to do the assertion in one line:

with_changeset(%User{})
|> assert_field(:email, ["test@example.com"], [nil, ""])

assert_field/4 could be implemented like:

def assert_field(changeset, field, valid_values, invalid_values) do
   changeset
   |> assert_valid_field(field, valid_values)
   |> assert_invalid_field(field, invalid_values)
end

Pros: a more concise syntax Cons: this could violate some people's 80 character column limit

If there is a :+1: on this I can implement
