Add ObjectRef::from as alias for ::from_obj

[nightkr]

Motivation

This allows things that rely on From/Into to perform the conversion implicitly. For example, we (@stackabletech) use ObjectRefs to normalize object path formatting in errors. When using SNAFU, this would simplify the error annotations from:

do_stuff().with_context(|_| ErrorCaseSnafu { pod: ObjectRef::from_obj(&pod) })?

to:

do_stuff().context(ErrorCaseSnafu { pod: &pod })?

Solution

The From impl just delegates to ::from_obj(). Maybe it would even make sense to deprecate ::from_obj, but I think it makes sense to keep it to highlight it as a first-class operation.
