Several issues with 'examples' module

There are several issues with the examples module in Ignite 3:

• README file is not updated (doesn't list newly added examples).
• Tests are included in packaging.
• SQL example should use try-with-resources for the server node, similar to other examples.
• Older RecordViewExample and KeyValueBinaryView examples should be removed and replaced with the versions that use the new client implementation ( ClientRecordViewExample and ClientKeyValueViewExample respectively).
• Example JavaDocs and outputs don't look complete and might require a review.
• If a table is created for an example, it should be dropped at the end. Otherwise, subsequent executions can fail.
• Logging is not formatted.
