[SPARK-25253][PYSPARK] Refactor local connection & auth code
This eliminates some duplication in the code to connect to a server on
localhost to talk directly to the jvm. Also it gives consistent ipv6 and error
handling. Two other incidental changes, that shouldn't matter:
1) python barrier tasks perform authentication immediately (rather than
waiting for the BARRIER_FUNCTION indicator)
2) for `rdd._load_from_socket`, the timeout is only increased after
authentication.
