Review request for atlas and Madhan Neethiraj.
Changes
-------
Added link to JIRA.
Bugs: ATLAS-1825
https://issues.apache.org/jira/browse/ATLAS-1825
Repository: atlas
Description (updated)
-------
Please refer to [ATLAS-1825|https://issues.apache.org/jira/browse/ATLAS-1825]
for scenarios and solution approach.
Impact
======
* New class _AtlasImportTransform_ is now part of _AtlasImportRequest_. This
holds a map of entity-type to attribute and the tranforms to be applied.
* New class _AtlasImportTransformBuiler_ reads the requests specified in the
query string of the import API and creates a _AtlasImportTransfor_ structure.
* _AtlasImportTransformBuiler_ has new classes that support transformations.
They are:
* _replace_ Implements find and replace on attribute values.
* _lowercase_ Converts attribute value to lower case.
* Additional classes that unit test these classes have been added.
Implementation Approach
=======================
* _ZipSource_ now accepts _AtlasImportTransform_ object. It applies the
transform every entity that is fetched from the source.

Testing
-------
**Unit Test**
* Added tests for *AtlasImportTransformBuilder* and contained classes.
* Updated *ZipSourceTest*
* Added tests to *ImportServiceTest* to exercise new option.
**Functional Test**
* Small size data export & import.
* Medium size data export & import.
**Performance Tests**
Not exhaustive. Simple stop watch tests to compare against baseline.
