Review Comment:
   Thanks for adding the comment. @sravani-revuri  Just thinking a bit more on 
this, is `close` the only local method here?
   
   It looks like  `getS3CredentialsProvider()` just returns a `ThreadLocal` 
with no RPC, yet it'd still read as `CLIENT`. Should we avoid inferring the 
span kind from the method name here? Would a method-level override/annotation 
for local operations be more robust while keeping remote protocol methods 
`CLIENT` by default? curious what you think.
