> UGI creates simple IOEs on failure, making it impossible to catch them, i=
gnore them, have smart retry logic around them, etc.
> # Have an explicit exception like {{KerberosAuthException extends IOExcep=
tion}} to raise instead. We can't use {{AuthenticationException}} as that d=
oesn't extend IOE.
> # move {{UGI}}, {{SecurityUtil}} and things related off simple IOEs and i=
nto the new one
> # review exceptions raised and consider if they can provide more informat=
ion
> # for the strings that get created, put them as public static constants, =
so that tests can look for them explicitly =E2=80=94tests that don't break =
if the text is changed.
> # maybe, {{getUGIFromTicketCache}} to throw this rather than an RTE if no=
 login principals were found (it throws IOEs on login failures, after all)
> # keep KDiag in sync with this
