redis_proxy: KEYS command hangs

[urusha]

Description:
KEYS command hangs with envoy redis_proxy, after such query envoy can't be killed normally by TERM,INT signals.

Repro steps:
debian 12 amd64, redis 7.4.1, envoy-contrib-1.33.0-linux-x86_64

echo 'SET test test123' | redis-cli -h 127.0.0.1 -p 6380 -a pass1
OK
echo 'GET test' | redis-cli -h 127.0.0.1 -p 6380 -a pass1
"test123"

while

echo 'KEYS *' | redis-cli -h 127.0.0.1 -p 6380 -a pass1

hangs forever, other queries continue to work, but after KEYS * query - envoy can't be killed by TERM,INT (KILL works).

Seems like some resource is not being released by the redis filter.
