Summary:
D4690225 added support for nested field name lookup in nested
`schema.Struct`s. It would throw a KeyError if trying to access a nested
`List`s field. Writing the lookup recursively avoids the need to enumerate
all complex field types in the lookup.

Summary:
We are having more and more nested Struct schema. There is increasing need to get/adda field by nested name, e.g., for the following nest Struct schema:
st = Struct(
('a': Scalar()),
('b': Struct(
('c': Scalar()),
)),
)
We may want to get the field "b:c" and/or insert a new field "b:x". The immediate need is for dper2 metrics.
This diff is to achieve this.

Summary:
Ievgen ran into this bug with his dper work - we didn't preserve metadata on lengths field.
Also, we didn't take keep_blobs into account for List's main field. Now fixed.
Also, reformat the file to be nice.
