Implement seek for read file parts

So that an upload part can be rewound and therefore
properly retried.

Fixes #401.
Allow resource ids for route53 to be passed in as returned by the service or in their canonical form.  Fixes #396.
Remove references to HealthChecks.  Those ID's do not include the resource name prefix when listed and therefore don't exhibit this problem.
