h2o python : On latest master(nightly) when there is a version mismatch get AttributeError: Attribute cloud_internal_timezone cannot be set on H2OCluster (= ‘America/Denver’) `

[exalate-issue-sync]

move the version check to earlier in the init function.

on - http://h2o-release.s3.amazonaws.com/h2o/master/4196/index.html
when use an older python client like - pip install http://h2o-release.s3.amazonaws.com/h2o/rel-wheeler/4/Python/h2o-3.16.0.4-py2.py3-none-any.whl

{code:java}

Nidhi Mehta commented: this happens when the h2o python version on client and server do not match(or strict version check is set to false)
