Description

We plan to support only one metric in 1.16 ( https://github.com/apache/madlib/pull/393 ) and that can be one of the supported metrics and not just accuracy. We should store the name of the metric that was computed (if computed) in the summary table.

There also seems to be a bug in reporting the model_size in the summary table, as it reports a drastically small number compared to the actual model learnt. Since that is also an update to summary table, it may be a good idea to fix it as part of this JIRA.
