Tested running this with a 4.0 running cluster, shutting it down and then
running `./accumulo zoo-zap -prepare-for-upgrade`.
Found that zooZap needs an update to the opts param check to allow upgrade
to be a valid option. Otherwise it just prints a usage statement.
Updated lines 115-119:
```
if (!opts.zapManager && !opts.zapTservers && !opts.zapCompactors &&
!opts.zapScanServers
&& !opts.upgrade) {
new JCommander(opts).usage();
return;
}
```
After fixing that, I could get zoozap to run but kept getting an exception
message when attempting to create the upgrade node.

Using zkCLI.sh, I can see that `upgrade_prepped` doesn't exist and the
accumulo instance path does.
