rgw: enhance radoslist to allow object & object version to be specified

[ivancich]

Previously radosgw-admin bucket radoslist ... could be run with or without a --bucket specified. Either way, if only the information for a single object is desired, there will be a lot of unwanted extra information. So the command is enhanced to optionally allow --object and --object_version to be specified. Each does the obvious thing. For example, on a versioned bucket if --object is specified but --object_version is not, it will produce a list of rados objects for all versions.

does this still have to process the entire bucket? maybe it's better to add a separate command like object radoslist that just reads a given head object and dumps the objects from its manifest

That was my original thought, but then you suggested "maybe just add support for the --object argument to 'bucket radoslist'" and I realized it could handle a seemingly useful case of a versioned bucket where the user specifies the object name but not the version id.

I could imagine leaving this as is, and adding the other way as well, but perhaps including additional information, such as pool.
