Remove "H2O API Extensions" in h2o.init() output in R and Python

[exalate-issue-sync]

There are too many extensions to fit on one line now, so we need a line break or something to clean up the output. It's too wide for the screen.

Michal Kurka commented: We can also hide: Core V3, Core V4, Algos - this is meaningless to the users

Erin LeDell commented: [~accountid:557058:04659f86-fbfe-4d01-90c9-146c34df6ee6] Ok, I can just keep the following, that’s cleaner, and sort alphabetically: {{Amazon S3, AutoML, Infogram, TargetEncoder, XGBoost}}

Erin LeDell commented: This data is generated on the backend, and so maybe we should just filter the “extra” ones out on the client side in R and Python in the {{list_api_extensions}} util function:

R: [https://github.com/h2oai/h2o-3/blob/dbdcc2b369ade409086626b05989da085c0a9c2b/h2o-r/h2o-package/R/communication.R#L729|https://github.com/h2oai/h2o-3/blob/dbdcc2b369ade409086626b05989da085c0a9c2b/h2o-r/h2o-package/R/communication.R#L729|smart-link]
Py: [https://github.com/h2oai/h2o-3/blob/36da4fc8b9c9e5baee2aec72a89b99a7d04bc3b5/h2o-py/h2o/backend/cluster.py#L192|https://github.com/h2oai/h2o-3/blob/36da4fc8b9c9e5baee2aec72a89b99a7d04bc3b5/h2o-py/h2o/backend/cluster.py#L192|smart-link]

Or we can only filter when printing to to the user in the {{h2o.init()}} printout, such as right here: [https://github.com/h2oai/h2o-3/blob/dbdcc2b369ade409086626b05989da085c0a9c2b/h2o-r/h2o-package/R/communication.R#L795|https://github.com/h2oai/h2o-3/blob/dbdcc2b369ade409086626b05989da085c0a9c2b/h2o-r/h2o-package/R/communication.R#L795|smart-link] and here: [https://github.com/h2oai/h2o-3/blob/36da4fc8b9c9e5baee2aec72a89b99a7d04bc3b5/h2o-py/h2o/backend/cluster.py#L282|https://github.com/h2oai/h2o-3/blob/36da4fc8b9c9e5baee2aec72a89b99a7d04bc3b5/h2o-py/h2o/backend/cluster.py#L282|smart-link]

[~accountid:557058:04659f86-fbfe-4d01-90c9-146c34df6ee6] Do you have a preference? My instinct is to filter only at print-out in case we want to use those util functions elsewhere and expect the full list.

Another thing i can do is remove underscores from Python printout (key names) to match R.

Michal Kurka commented: [~accountid:557058:afd6e9a4-1891-4845-98ea-b5d34a2bc42c] I am thinking we should just completely drop the “H2O API Extensions” line from the output

I don’t see how it is useful

[exalate-issue-sync]

Erin LeDell commented: [~accountid:557058:04659f86-fbfe-4d01-90c9-146c34df6ee6] Ok, I am fine with that. Anything else that we want to get rid of? Do people use the “H2O Internal Security”? I am not sure what that’s for..

[exalate-issue-sync]

Michal Kurka commented: I would keep the other stuff - at least for now, it is useful for debugging sometimes

The extension list is always the same,users do not add extensions and don’t disable them
