Typings for Field attributes

[kalekseev]

Currently a lot of Field's attributes are not exposed in types, eg:

error: "ChoiceField" has no attribute "field_name"
error: "Field" has no attribute "allow_blank"
error: "Field" has no attribute "allow_null"
error: "Field" has no attribute "default"; maybe "get_default"?
error: "Field" has no attribute "read_only"
error: "Field" has no attribute "required"

that cause a lot of headache when serializers modified dynamically.

@sobolevn I would like to fix this. I'll provide a PR that passes the pipeline.

[kalekseev]

@stevanmilic I created a pr but it wasn't merged and after some of the fields were fixed in master it has merge conflict. You can use that pr as starting point.

@kalekseev I've just taken a look at master branch, it looks like the attributes are added in 2112425#diff-279543faf36724e6286925cb91487e5e commit, we can close this issue.

Yes, I have merged it today. Sorry for the delay!
