> ClientContext::get gets the context from CACHE via a config setting based name, then
KeyProviderCache stored in ClientContext gets the key provider cached by URI from the configuration,
too. These would return the same KeyProvider regardless of current UGI.
> KMSClientProvider caches the UGI (actualUgi) in ctor; that means in particular that all
the users of DFS with KMSClientProvider in a process will get the KMS token (along with other
credentials) of the first user, via the above cache.
> Either KMSClientProvider shouldn't store the UGI, or one of the caches should be UGI-aware,
like the FS object cache.
> Side note: the comment in createConnection that purports to handle the different UGI
doesn't seem to cover what it says it covers. In our case, we have two unrelated UGIs with
no auth (createRemoteUser) with bunch of tokens, including a KMS token, added.
