> [~romil.choksi] found a test issue where ShellServerIT.getAuths() would intermittently
fail.
> This is because of the use of ZooCache inside of ZKAuthorizor. The minicluster has two
tabletservers. If the shell is so unlucky to update the authorizations on one tserver but
then ask for the authorizations on the other tserver, the test is subject to the propagation
of the ZK watcher update to fire.
> We should just switch over ShellServerIT to run a minicluster with only one tserver than
try to hack around this in the test itself with retries.
