Adding FAST option to DEBUG OBJECT command.

The light version only shows the light weight infomation,
which mostly O(1). The pre-existing version that show more
stats such as serializedlength sometimes is time consuming.

This should allow looking into debug stats (the key expired
but not deleted), even on huge object, on which we're afraid
to run the command for fear of causing a server freeze.

Like 3ca451c.

The light version only shows the light weight infomation,
which mostly O(1). The pre-existing version that show more
stats such as serializedlength is reachable with the `full`
argument.

This should allow looking into debug stats (the key expired
but not deleted), even on huge object, on which we're afraid
to run the command for fear of causing a server freeze.

Like 3ca451c.

This is not backward compatible, but we don't need backward compatibility for DEBUG?

yes, it is for debug, i don't think we need backward compatibility for it.

Why not make it backward compatible though? I found a few examples of AWS using it internally for testing that would fail on rdbSavedObjectLen(). Those are easy to fix, but maybe someone else is using that as well. We could easily make it backwards compatible and do DEBUG OBJECT FAST no?

the default behavior is a bit dangerous, like act on a large lists, but i guess the DEBUG is already dangerous in usually, DEBUG OBJECT FAST looks good to me, i will change it
