USER_AUTHENTICATION_ENABLED means the drill's client is logging in drill as 
some authenticated users, but enabling zookeeper ACL means we are going to 
protect our znodes using ACL. so other user should not be able to modify our 
znodes, I think this is a valid scenario, meaning no warning needed.

This approach encodes the meaning of paths in just the path name. Seems 
fragile.

Alternatives:

* Register the secure (or insecure) paths so that the ZK cluster 
coordinator (not this class) decides on security.
* Get ACL base on type: `getSecureACL()` or `getPublicACL()`, and let the 
cluster coordinator define which is which.
* As a refinement of the first idea, provide some kind of config option to 
externalize the set of paths and their security.

For example, in Drill-on-YARN, the app master creates ZK entries to ensure 
that only one app master starts per cluster. We would not want to encode that 
path information here.

Encoding path building here seems fragile. The ZK cluster coordinator 
should build the path, then pass that along to the factory, which passes it 
here. Simplifies things if we ever have to change how we construct the path if 
we create it in one place rather than two (or more).

`use.secure_acl` --> `secure_acl` as `use` is not a group. This provides:

```
  zk: {
connect: "localhost:2181",

```

Are we using ACL's for security? Then, we are really "applying" ACLs, so 
maybe `apply_acl` (apply an access control list...)

This needs to be set to true in 
`/opt/mapr/drill/drill-1.11.0/conf/drill-distrib.conf` by `configure.sh` when 
security is enabled on a MapR cluster. Do we have a tracking work item for this?
