Incorrect default uid/gid

[avanide]

Describe the bug
The dockerfile is using uid 1000 which is considered as a bad practice. The default uid/gid should follow security recommendations (>=10000).
I've noticed the related link: #89
The point is that it should be default.

To Reproduce
Just check the Dockerfile:

• https://github.com/31z4/zookeeper-docker/blob/master/3.8.4/Dockerfile (uid & gid to 1000)
• https://github.com/31z4/zookeeper-docker/blob/master/3.9.2/Dockerfile (same)

Expected behavior
Many security tools considers using a uid >= 10000 is recommended to reduce the likelihood of privilege escalation.
