Description of problem:

Why a redis database is getting installed with the default RHUI installation? It seems to being used. Can this package be removed?

[root@rhua proc]# ss -antpl |grep redis
LISTEN 0      511        127.0.0.1:6379       0.0.0.0:*    users:(("redis-server",pid=949,fd=6))

[root@rhua02 proc]# ps -ef |grep redis
redis        949       1  0 May05 ?        02:07:14 /usr/bin/redis-server 127.0.0.1:6379

### no database configured
[root@rhua proc]# redis-cli info keyspace
# Keyspace

# data location is empty
[root@rhua proc]# redis-cli config get dir
