Support schema types with non-str value

Change I75da1e9309e0f7ef8839dea3ec9c99c58edc5d63 introduced some
properties' types which are not string. This broke the `schema_args`
utility since lists are not hashable and there was no support for such
type values.

This patch fixes this issue with a very glance specific strategy in
which this values are assumed to have a `null` type and another type -
string, integer, etc. The fix ignores `null` options and it takes the
first non-null type as the valid one.

The patch adds support for enum types that accept `None`
