[SYSTEMDS-2661, 2662]: Data Cleaning Pipelines Version 1 Pipelines Optimizer and various minor built-ins This commit contains, 1. Optimizer for cleaning pipelines 2. Minor built-ins imputeByMean, imputeByMedian, frameSort, vectorToCsv.dml 3. minor fixes for resolving warnings in different dml scripts 4. Deletion of bandit and enumerator test (ac they are combined in cleaning test) and airbnb dataset 5. basic support for as.frame() for lists 6. null inside as.matrix() will be converted to NaN Closes #1115.

Overview: SystemDS is a versatile system for the end-to-end data science lifecycle from data integration, cleaning, and feature engineering, over efficient, local and distributed ML model training, to deployment and serving. To this end, we aim to provide a stack of declarative languages with R-like syntax for (1) the different tasks of the data-science lifecycle, and (2) users with different expertise. These high-level scripts are compiled into hybrid execution plans of local, in-memory CPU and GPU operations, as well as distributed operations on Apache Spark. In contrast to existing systems - that either provide homogeneous tensors or 2D Datasets - and in order to serve the entire data science lifecycle, the underlying data model are DataTensors, i.e., tensors (multi-dimensional arrays) whose first dimension may have a heterogeneous and nested schema.
