Increment the number stored at field in the hash at key by value. If key does not exist, a new
key holding a hash is created. If field does not exist or holds a string, the value is set to 0
before applying the operation. Since the value argument is signed you can use this command to
perform both increments and decrements.

The range of values supported by HINCRBY is limited to 64 bit signed integers.
