Redis password should be set to `null` about osctrl

[CptOfEvilMinions]

md5 osctrl-tls-linux-amd64.bin
MD5 (osctrl-tls-linux-amd64.bin) = da5429cbe90de8b0c8b35e63907c5091

When I don't set the ENV var REDIS_PASS I am still getting the same errors.

#248 fixed issue above.

Do you want me to skip the password if it is set to empty string?

[CptOfEvilMinions]

Correct, if REDIS_PASS is not set then just assume there is no password.

docker-compose:

 osctrl-tls:
    container_name: 'osctrl-tls'
    restart: unless-stopped
    image: jmpsec/osctrl-tls:v${OSCTRL_VERSION}
    environment:
     ...
      #### Redis settings ####
      - REDIS_CONFIG=false
      - REDIS_HOST=redis
      - REDIS_PORT=6379

log output:

osctrl-tls             | main.go:381: Connection to backend successful!
osctrl-tls             | main.go:390: Initializing cache...
osctrl-tls             | main.go:393: Failed to connect to redis - ERR AUTH <password> called without any password configured for the default user. Are you sure your configuration is correct?
osctrl-tls exited with code 1

Now the value for the Redis password if not modified by JSON, paramenter or env is empty.

[javuto]

Is the line requirepass removed from the Redis configuration?

BTW no need to set REDIS_CONFIG since the value is false by default.
