Python API is missing methods from REST API

[amesar]

A number of REST API methods are not implemented in the Python API.

• get_experiment - https://mlflow.org/docs/latest/rest_api.html#get-experiment
• get_metrics - https://mlflow.org/docs/latest/rest_api.html#get-metric
• get_metrics_history - https://mlflow.org/docs/latest/rest_api.html#get-metrics-history
• search - https://mlflow.org/docs/latest/rest_api.html#search-runs

Documentation links:

• Index of Python API methods - https://mlflow.org/docs/latest/genindex.html
• REST API - https://mlflow.org/docs/latest/rest_api.html

get_experiment is added in #299.

get_metric and get_metrics_history (and get_param) are currently a bit weird to expose from the REST API standpoint, as they are subsumed by get_run, so it would be exposing 4 APIs where one suffices. Obviously as we get larger runs with larger sets of metrics and parameters, we may want to revisit this, but at that point we should also refactor get_run not to be some potential landmine API that could explode the client. Maybe @mateiz has some opinion on the place of those three additional APIs.

search I agree without reservation that it should be added in the current Python API -- but this is the most complicated API, and maybe, as you pointed out here, we should simplify it before exposing.

Any update on this issue? Thanks

I think these are all implemented now. Closing issue.
