Fix redis_tls_proxy

Since we merged the pcs-host patches we erroneously also removed
the sidecar container that does the tls stunneling for redis.
This is needed to allow the redis master stream the deplications to
its slaves via TLS.

Tested this and we now correctly get the working container and cluster
state:
[root@controller-0 ~]# podman ps -a |grep redis

    * redis-bundle-1    (ocf:💓redis):  Slave controller-1
    * redis-bundle-2    (ocf:💓redis):  Slave controller-2

We also move the redis_tls_proxy from step_2/start_order: 3 to step_1
since it actually makes sense to have it run before we start the
redis pcmk bundle at step 2 (i.e. so the slave replica can work right
away from the start).
