LREM key count value

Removes the first count occurrences of elements equal to value from the list stored at key. The count argument influences the operation in the following ways:

For example, LREM list -2 "hello" will remove the last two occurrences of "hello" in the list stored at list.

Note that non-existing keys are treated like empty lists, so when key does not exist, the command will always return 0.

*Return value

Integer reply: the number of removed elements.
