RFR: 8368493: Disable most JSSE debug output by default, and increase the default maximum output log size

[Bradford Wetmore]

See the bug for more info.  This will allow for:

1. extra/unneeded JSSE debug output will not be added to each test run, saving space and noise.
2. make it easier to get the full JSSE debug output when enabled.
