manifest_xml: refactor manifest parsing from client management

We conflate the manifest & parsing logic with the management of the
repo client checkout in a single class.  This makes testing just one
part (the manifest parsing) hard as it requires a full checkout too.

Start splitting the two apart into separate classes to make it easy
to reason about & test.
