allow forceVersion false for command line client

, would you please have review and merge the change?

Code looks good.

Does this needed too be released soon( as in version 1.9.4 instead of 2.0.0)? If not, please check in to the develop branch and resolve merge conflicts. We only use the master branch to track the current release (1.9.3) so if a 1.9.4 is needed, we need to make a 1.9.4-rc branch

Yes, along with a handful of other outstanding PRs that have been open for nearly a year. We need to release faster so that we can use the changes.

Which other PRs still need to be merged and released?
If any have already been merged, then they would have gone in to the develop branch, which would warrant a 2.0 release. So far the only major change from 1.9 to 2.0 is the removal of python 2 support.

Can I mark this resolved/closed, ? Thanks!
