interpreter.json value recording

JDBC interpreter settings are not recorded correctly in interpreter.json: in my case, Zeppelin keeps storing zeppelin.jdbc.maxRows and common.max_count as "10000.0" which then throws an error when the driver tries to execute SQL commands. Also, dependencies (e.g. mysql Driver jar) are not stored in interpreter.json. Probably a small thing to correct, but this should be fixed ASAP as it makes Zeppelin unusable.

By the way, I tried to change the values directly in the interpreter.json file, but the "10000.0" kept coming back after restarting Zeppelin.
