Support EXPLAIN on Greenplum. Fixes #3097

- Extract SQLEditor.execute and SQLEditor._poll into their own files and add test around them
 - Extract SQLEditor backend functions that start executing query to their own files and add tests around it
 - Move the Explain SQL from the front-end and now pass the Explain plan parameters as a JSON object in the start query call.
 - Extract the compile_template_name into a function that can be used by the different places that try to select the version of the template and the server type
