Robert Muir 027730006b core: add 'checksum' option for index.shard.check_on_startup
The current "checkindex" on startup is very very expensive. This is
like running one of the old school hard drive diagnostic checkers and
usually not a good idea.

But we can do a CRC32 verification of files. We don't even need to
open an indexreader to do this, its much more lightweight.

This option (as well as the existing true/false) are randomized in
tests to find problems.

Also fix bug where use of the current option would always leak
an indexwriter lock.

Closes #9183
