Start script improvements

[jsoref]

• it's possible to end up w/ "Windows" line endings in ongdb.conf and when that happens running the unix ongdb release script with that file results in a very unhappy system. Tolerating those line endings seems reasonable, as users generally expect conf files to be portable and not to need to worry about line endings.
• one should be able to run ongdb version without java preallocated gb's of memory for ongdb -- we have containers that run with enough space for one copy of ongdb but definitely not enough space for two copies of ongdb, but it should be possible to run ongdb version as that doesn't require the preallocation defined in ongdb.conf -- Simplify the start script to do minimal work when getting version (skipping setup_java_opts, most of setup_arbiter_options).

These changes seem reasonable to me. I'm good with both of them. Build is failing during testing of server assembly. I think we discussed elsewhere that test expectations need updated following the changes to the version command.
