Summary: - When options file is provided to db_stress, take supported options from the file instead of from flags - Call `BuildOptionsTable` after `Open` so it can use `options_` once it has been populated either from flags or from file - Allow options filename to be passed via `db_crashtest.py` Closes https://github.com/facebook/rocksdb/pull/3768 Differential Revision: D7755331 Pulled By: ajkr fbshipit-source-id: 5205cc5deb0d74d677b9832174153812bab9a60a

DUMP_FORMAT.md
## RocksDB dump format
The version 1 RocksDB dump format is fairly simple:
1) The dump starts with the magic 8 byte identifier "ROCKDUMP"
2) The magic is followed by an 8 byte big-endian version which is 0x00000001.
3) Next are arbitrarily sized chunks of bytes prepended by 4 byte little endian number indicating how large each chunk is.
4) The first chunk is special and is a json string indicating some things about the creation of this dump. It contains the following keys:
* database-path: The path of the database this dump was created from.
* hostname: The hostname of the machine where the dump was created.
* creation-time: Unix seconds since epoc when this dump was created.
5) Following the info dump the slices paired into are key/value pairs.
