Description

Remove flink_submit_uber_jar option and instead use this logic:

(1) If no options are provided, a local flink cluster is started up and is used,
(2) If a master is specified, we submit it to that job in the least intrusive way possible (ie, via the Flink uber jar job server)

Imported from Jira [BEAM-9986](https://issues.apache.org/jira/browse/BEAM-9986). Original Jira may contain additional context.

Research direction

No files or tests are named. Start by locating the --flink_submit_uber_jar option and its handling, then trace how local Flink clusters and specified masters are selected. Done means the option is removed, no-option runs use a local cluster, and specified masters use the Flink uber jar job server with minimal intrusion.
