Package Name Change

[rominparekh]

Issue: #53

This PR:

• Changes package name from com.netflix.iceberg to org.apache.iceberg
• Java and Scala style formatting is not changed
• I've tried my best to not remove any unused imports. If you find any missing and want to add it back, I'm happy to accommodate your feedback.
• Changes made to gradle.build and TestSparkReadProjection files to detect change in packaging source respectively
• I understand this impacts any in-flight PRs but I feel it's better to get this in sooner than later.

Reviewers, I request you to prioritize this change to avoid merge conflicts. Thank you. :)

@rominparekh #69 and #28 are open, and have similar goal: to rename Iceberg to apache packages, and to fix/start enforcing a coding standard.

@xabriel thank you for sharing those PRs. I was not aware it was already covered. Closing this .
