Add manifests to install and configure stunnel
Some services (such as Redis) can't use mod_proxy as a TLS proxy, since they're not HTTP services. So stunnel is necessary for these. Thus, we add manifests to configure it as such. bp tls-via-certmonger Change-Id: Ic4a2dac7b3831e4780105e3b05e9c5afcf15c79c (cherry picked from commit f85199c77826017e383534051ada57ef1ea4ddcc)
