thaw with updated template
Hi,
I want to get your opinion on whether 'thaw' command should support the
specification of template, as in:
--template appConfig.json
The use case would be: user changes some (hbase) config values and wants
the new values to take effect when the cluster is thaw'ed.
Please comment.

I think Steve’s idea of a warning should suffice.

It would get merged with the cluster config in the cluster instance config
in HDFS.

For separate option, where would updated template be stored ?

Separate option seems good. Should Slider block update if its a running
cluster?

I think it might be a separate option, the way flex is.
something like
slider update cluster --template {other args}
This would make it easier to patch things. It'd have to warn on a patch of
a running cluster "changes will not take effect", but otherwise just
load/patch/save the config(s)
