Description

Currently, adding and removing an auth presents a race condition because of the two separate calls required to get, modify, then set the authorizations for a user.

Instead, it should be possible to add or remove one or more auths without there being a race condition.

I also propose adding two new commands to the shell to expose this functionality.

It appears to be that this is not a difficult feature to add, by making use of ZooReaderWriter.mutate() in the FATE packages. I think the bulk of the work will be in changing the various interfaces (shell and programmatically) to expose this functionality.

I would like to do this work and I'm a accumulo newbie, so any guidance would be appreciated.
