Python: make it possible to not print out model information

[exalate-issue-sync]

In python client, there is currently no way of suppressing output.

One major reason is the implementation of our {{repr}} which prints instead of returning a string as other tools such as PyCharm’s IPython console expect which causes printing of model details to the console even when just using the variable inspector.

Another reason is just printing the model information in functions such as {{h2o.upload_mojo}}.
