lovro 8a46ecd357 WriteBatch::Put() overload that gathers key and value from arrays of slices 
Summary: In our project, when writing to the database, we want to form the value as the concatenation of a small header and a larger payload.  It's a shame to have to copy the payload just so we can give RocksDB API a linear view of the value.  Since RocksDB makes a copy internally, it's easy to support gather writes.

Test Plan: write_batch_test, new test case
