IDECRBY work just like {@link #decr(string) INCR} but instead to decrement by 1 the decrement
is integer.
<p>
INCR commands are limited to 64 bit signed integers.
<p>
Note: this is actually a string operation, that is, in Redis there are not "integer" types.
Simply the string stored at the key is parsed as a base 10 64 bit signed integer, incremented,
and then converted back as a string.
<p>
Time complexity: O(1)

@param key
@param decrement
@return Integer reply, this commands will reply with the new value of key after the increment.
